for the question at 6:25 I think the answer is 8 which is not in the choices. my formula is b(a+c) = d, where a = right vertex, b= center, c = left vertex and d= top vertex. it applies to the first two triangle and when applied to the 3rd one it looks like this. 8(5+c)=104, which gives c = 8. therefore the answer is 8.

yes, as per pattern addition of the first operand numbers multiplied by 2nd operand gives the answer, but 4th expression should 27, options don't have it
for the question in 7:44, on the left side of the triangle from bottom to top, we got (8, 4, 3), on the right side from bottom to top, we got (2, 6, ?), so, bottom 8 and 2, middle 4 and 6, top 3 and ?... the logic: bottom sum 8 + 2 = 10, middle sum 4 + 6 = 10, so the top sum will also result in 10, ... the solution (3 + ? = 10) -> (? = 10 - 3) -> (? = 7)
Wow i reached the same conclusion but used a different method. right (8, 4, 3) left (2, 6, ?). the right side is decreasing and left side is increasing by the same amount, first 4 then 1. right side (8 - 4 = 4) (4 - 1 = 3), left side (2 + 4 = 6)(6 + 1 = 7) so the answer is 7.
For John's spending, I find it easier to get percentage of what john hasn't spent on and then directly multiply to get the final answer in dollars. This is easier than calculating with dollars from the beginning. utilities is 40%, heating is 15% higher than utilities. So multiply 40% x 1.15 and you'd get the percentage for heating directly (or alternatively 40% + 0.15 x 40% = 40% + 6%= 46%). utilities - 40%, heating 46%. So together it adds upto 86%. That means he spends 14% on things other than Utilities or heating (100-86). now, $1500 x0.14= $210.

A mental math trick for multiplying by 1.15 is to first multiply by 10 and then add half of that and then divide by 100. So, for 600 x 1.15...do 600 x 10 = 6000 then add half of that which makes it 9000...then divide by 100 which is 90 so answer is $690 for electricity and heating.
John total monthly spending is $1500. 40% is utilities. ( 40% is $600 ) 15% more in heating and electricity then utilities . ( 15% of 600 is 90 ) remaining spend is = $1500 - $600 - $690 = $210
5:15 John Spent $210 on Other (Util = 1500 * 40% = 600, Heat&Elec = 600 + 15% of 600 = 690, Other Spent = 1500 - (600 + 690 = 1290) = $210 which is the answer.

It’s a poorly worded question because heating and electricity are utilities, so you could take this as a trick question, but the choices lead you to know it’s a poorly worded question with no intent of trickery just stupidity
13:29 Again, another error? Someone please correct me if I'm wrong?🙏🏾 The pattern is clear; Add the first two digits(xx), then multiply(*) by the single digit; (1+8) x 3 = 27 (1+2) x 4 = 12 (2+2) x 8 = 32 Therefore, the answer ideally should be: (1+2) x 9 = 27 🤷🏽♂️ , not 36
19:00 Using velocity = distance / time (ie. v = d / t) How long(t) will Olivia walk to ensure that her distance-covered equals distance-covered of Kiara?🤔 We can also say: "how long(t) will both of them walk till their distance-covered become equal?" The preceding statement reduces the unknowns to one variable, and this is 't'. 🤔 ? See below: distance-covered of olivia = distance-covered of kiara ie. vt - 4 = v * t (where 'vt - 4' is from 8 = (d + 4) / t) 8t - 4 = 5t 3t = 4 t = 4 / 3 t = 1.33333333 hrs convert to minutes, you get appr. 80minutes. So, they both have to walk for 80 minutes to be at same position

John's total expenditure is $1500, outof which utilities is 40% means 1500*40/100=600 and Heat & electricity is 15% more than Utility bills i.e 600*15/100=90 and total Heat & electricity is 690, so expenditure on Utility & heat & electricity are 600+690=1290, so other expediture is 1500-1290=$210
For the question at 6:25, If the answer should be from the given options then it should be option B) 10 and instead of '5' in 3rd triangle it should be '3'. => (3*8) + (8*x) = 104 => 24 + 8x = 104 => x = (104 - 24)/8 => x = 80/8 => x = 10 Or if the numberings are correct in the 3rd triangle, then the options are not correct and there should be '8'. => (5*8) + (8*x) = 104 => 40 + 8x = 104 => x = (104 - 40)/8 => x = 64/8 => x = 8
Regarding the question if speeds is simpler. Subtract one speed from the other. 8-5=3 mph (relative speed) The problem is equivalent as one stoped and the other walking at 3mph. This new equivalent problem demands the time when they met. So speed is displacement over time. Displacement is 4 and speed is 3. So the time is 4/3 of hour that is 80 mins.
@@crystalsports1331 Basic physics. If I want to solve the problem of speeds you must first find the relative speed between the two persons. This is done by subtracting the speeds. 8-5=3. So 3 is the relative speed. Then the problem becomes simpler. You will assume the person is 4 units of length ahead of you and still because you are moving in relation to her at 3mph. The definition of speed is displacement over time. So time is displacement over speed. This gives the value 4/3 that is the time. When converting to mins we will get 80 mins.
@19:00 When Olivia will catch up, Kiara and Oliva will have walked the same time t. 1- For Kiara, t = d/5 where d is the distance she will walk until Olivia catches up => d = 5t 2- For Olivia, t = (d+4) / 8 since she started 4 miles behind. => 8 t = d+4 => d = 8t - 4. from 1 and 2 : 5t = 8t -4 => t = 4/3 in hours thus (60*4)/3 = 80 minutes.
Total spending = $1500 while 40% of it for utilities = 0.4 * $1500 = $600 and cost of heating and electricity is 15% higher than cost of utilities = $600 * 1.15 = $690 therefore the cost of other spending other than heating, electricity, and utilities = $1500 - $600 - $690 = $1500 - $1290 = $210
7:45 The right (8, 4, 3) left (2, 6, ?). the right side is decreasing and left side is increasing by the same amount, first 4 then 1. right side (8 - 4 = 4) (4 - 1 = 3), left side (2 + 4 = 6)(6 + 1 = 7) so the answer is 7.
the correct anwer will be 10, because for the right side we make {3+1=4} and 3+4 = 7 and 7+1=8 for the other side we make 2+4=6 and which mean that we add 4 only and after that we make 6+4= 10
Thank you for sharing this video. It’s very insightful. I have an observation :Question at 30:35 minutes has a typo. The left bottom number of the 3rd triangle should be 3
At 20:20 you can simplify this, does not matter how far Kiara walks, what matters is Olivia walks 3mph faster than Kiara and needs to catchup 4 miles so you know that is 4/3 hours which is 80 mins
The question for 22:42 18 * 3 = 27 12 * 4 = 12 22 * 8 = 32 12 * 9 = ? ( it should be 13 not 12 ) Answer for 12 * 9 = 27 Answer for 13 * 9 = 36 But all good! You are still Awesome!

For the question at 32:49, I find it easier using BODMAS avoids confusion in the PEMDAS as division comes first. PEMDAS works in the first step if we use the left to right rule
John spending 40% of utility =600 Utility=electricity +heat expense which is 15% high Electricity +heat=600*115%=690 Other expense =1500-600-690=210 Answer

At 17:50 it would be simpler to calculate total rent by taking the increase of 260 multiplying by 4 to give the increase for remaining students and multiplying by original students i.e. 260*4*5 = 5200, no need to do all those steps
The answer to question at 6:25 is 8 not 10. Though 8 is not one of the choices. In answering the question, you had used 3 as the number at the bottom of the triangle instead of 5.
PEDMAS is a new term for us Indians who went to school in 90s. We have been taught BODMAS (B= Brackets, O = Orders ie powers, indices or roots, D: Division, M: Multiplication, A: Addition, S: Subtraction.
5:31 John's total monthly spending is $1500. 40% of his spending goes towards utilities: Utilities = 40% of $1500 = $600 The amount he spends on heating and electricity is 15% higher than what he spends on utilities: Heating and Electricity = $600 + 15% of $600 = $600 + $90 = $690 To find the amount John spends on things other than heating, electricity, and utilities, we subtract the amounts spent on utilities and heating/electricity from his total spending: Other Expenses = Total Spending - Utilities - Heating and Electricity = $1500 - $600 - $690 = $210 Therefore, John spends $210 on things other than heating, electricity, and utilities.
Well done! Your participation in the challenge is valued, and your answer reflects your dedication. Best wishes for a successful job interview and assessment test. Keep up the great work and continue reaching for your goals!
For John, 40% expenditure in utility is 40/100 * 1500 = 600. He spends on heating and electricity 15% more than utility which is 115/100 * 600 = 690. The remaining is 1500 - (600 +690) = 210
The problem in majority question I take about a minute or 30-50 sec, and the test requires 18 sec on average for each question. Rare questions I finish before the average 18 sec to give me time for the other questions
0.4 for utilities, for heating and Electricty 0.15 of 0.4 = 0.06 +0.4=0.46, 0.46+0.4=0.86, What John spends on other things 1.00 - 0.86= 0.14 of 1500 = 210
Explanation at 24:24 the problem indicated 12*9=?, but the solution they solve 13*9. Just saying that's why the answer didn't much the choice if we solve it.
2:09 Technically, it is 174% not 274%. Does it matter? Yes, especially when you are computing financial data. 218 is the increase "by" --174% 343 is the increase "to" --274% It is grammar, and is widely known in the industry. Please correct me.
13:30 The answer should be 27 The idea is to add the first two digits, then multiply the sum by the second operand (part) so 1+8 = 9, 9 * 3 = 27; 1 + 2 = 3, 3 * 4 = 12; 2 + 2 = 4, 4 * 8 = 32; lastly 1 + 2 = 3, 3 * 9 = 27 just like the first line.. which doesn't exist between the answers and not 36 as you chose... Else please elaborate further. Why confuse us with wrong answers?
Год назад+1
He shared a different question and solved a different one at 23:05. Your answer isn't wrong, it's the question that is wrong. 😂
The maths questions dont need to be answer exactly as implied on 2:02 and 4:33. You dont have the time for that. In this case you just need to know that 343/125 is a number that begins by 2XX (since 125 only divides into 343 two times) then you can discard all other answers. Same as 33 x 5. Tha correct answer is a number that ends with a XX5 (only 1 answers is a number ending in 5, which is 165). Usually, math questions with such little time require a quick calculation that aims at a single correct option, without knowing all the digits of the operation or the exact result.
for the pyramid problem we can solve it in 3ways 1st one is sum of left side numbers should be equal to right side which replace ? with 7 and 2nd way is some of opposite side of triangle should be equal like 8 from left and 2 from right their some is 10 and 4 from left and 6 from right the sum is 10 and it leaves us with 3 from left and ? from right which gives us 7. sorry guys if im wrong.
at 7.19 the explaination doesn't seem correct. the number on the triangle at the bottom right is 5 and not 3.... the answer of the missing number should be 8 and not 10. (5+8)*8=104
- Jone spend on thing other than heating, electricity and utilities is $210 it calculated by his spending on utilities (40%*1500= 600) / his spending on heating & electricity (600*15%=90+600=690) finally 1500-(690+600)= 210
5:20 answer is wrong. John's total monthly spending is $I500 of 40% of his spendings goes towards utilities. And the amount that he spends on heating and electricity is 15% higher than what he spends on utilities. Answer is => 1. Total Monthly Spending: $1500 2. Utilities Spending: $1500 * 0.40 = $600 3. Additional Spending on Heating and Electricity: 15% * $600 = $90 4. Total Spending on Heating and Electricity: $600 + $90 = $690
The question that you used PEMDAS for, we were taught in my country to use BODMAS which means Bracket, Of, Division, Multiplication, Addition, and Subtraction. If I use that, the answer would be 3

The question about John's spending at 5:24 is a red herring. At least in the US, heating and electricity are considered utilities so the question makes no sense.

Really I was going through this video One thing I observed is all simple questions are solved and lil complex questions are given for comment section in which most of the options are wrong.
7:18 there might be an error here? Someone kindly confirm/correct me?🙏🏾 At the bottom left of the 104 Triangle, it is *5 in the question, not 3; so it should be: 104/(5 + ?) = 8 104/8 = (5 + ?) 13 = (5 + ?) 13 - 5 = ? ? = 8
At : 16:32 Before 5,200 / 5 = 1040 After student left earlier : Case 1 : 1040 / 4 = 260 Case 2 : 3120 / 4 = 780 Case 3 : Obviously no need to check because this is lower than case 2 which will increase the amount Case 4 : Same as Case 3 Answer should be A.5,200
At 24:20 I do not think this is a good example question as 27 is also a valid answer using a different pattern, no way a candidate taking the test can determine which pattern is correct: (1+8)*3 = 27 (1+2)*4 = 12 (2+2)*8 =32 (1+2)*9 = 27

@@goodvibes4351 8 is actually the correct answer for the triangles question. He mistakenly used 3 for the bottom calculation instead of the 5 that is written there.
John's question could be interpreted wrongly as one spending is 15% more percentage wise than 40% meaning 55%, making all his expenses 95%, however, it should be 40 * 1.15 = 46%, nice and tricky question! The answer is A, 210 USD.
@@Steph_Space I got the answer B through process of elimination. All the right hand side numbers are divisible by the second left hand side number (e.g. 32 is divisible by 8 for the 3rd row). All the choices are not divisible by 9 except 36 (option B).
Surely for a word scramble there should only be one possible answer? You stated BOWL was correct, but BLOW is also a valid answer. Should have a better example...

Most of the questions have something wrong with them. Like, in the triangles one There is written 5 instead of 3. In the 'can you calculate' one 12*9 is written instead of 13 and so on. No wonder we're getting the answers wrong
If you add 274 percent to 125 then the value will be 467.5. Which is incorrect. Correct formula will be - New volume - old volume __________________________ x 100 Old volume

The triangle has the number 5, but in the formula you put number 3
I also got 8. In the explanation, he accidentally typed 5 instead of 3...so his answer was off by 2.
question at 13:27 seems to be having wrong options, seems ans should be sum of two digit multiple by other number which should be: (1+2)*9 = 27
I agree
Got the same
agree

yes, as per pattern addition of the first operand numbers multiplied by 2nd operand gives the answer, but 4th expression should 27, options don't have it
for the question in 7:44, on the left side of the triangle from bottom to top, we got (8, 4, 3), on the right side from bottom to top, we got (2, 6, ?), so, bottom 8 and 2, middle 4 and 6, top 3 and ?... the logic: bottom sum 8 + 2 = 10, middle sum 4 + 6 = 10, so the top sum will also result in 10, ... the solution (3 + ? = 10) -> (? = 10 - 3) -> (? = 7)

Right I am come up with the same answer.
For John's spending, I find it easier to get percentage of what john hasn't spent on and then directly multiply to get the final answer in dollars. This is easier than calculating with dollars from the beginning.
utilities is 40%, heating is 15% higher than utilities. So multiply 40% x 1.15 and you'd get the percentage for heating directly (or alternatively 40% + 0.15 x 40% = 40% + 6%= 46%).
utilities - 40%, heating 46%. So together it adds upto 86%. That means he spends 14% on things other than Utilities or heating (100-86).
now, $1500 x0.14= $210.

A mental math trick for multiplying by 1.15 is to first multiply by 10 and then add half of that and then divide by 100. So, for 600 x 1.15...do 600 x 10 = 6000 then add half of that which makes it 9000...then divide by 100 which is 90 so answer is $690 for electricity and heating.
Thank you so much...i was lost with this one.
John total monthly spending is $1500.
40% is utilities. ( 40% is $600 )
15% more in heating and electricity then utilities . ( 15% of 600 is 90 )
remaining spend is = $1500 - $600 - $690 = $210
Awesome job! You got it!!!
i believe there's an error on 7:29. The image has the numbers 104, 8, and 5 on the triangle, while the solution has the number 3 instead of 5.
I noticed the same thing. Where did the 3 come from....it should be 5
if you take that missing number as "x" 5*8 + 8*x = 104...... x = 8...........Answer is 8
yess , i noticed the same thing , the answer is 8
I think so, the procedure is correct but the used number, 3, is wrong.
i was looking for this comment.
5:15 John Spent $210 on Other (Util = 1500 * 40% = 600, Heat&Elec = 600 + 15% of 600 = 690, Other Spent = 1500 - (600 + 690 = 1290) = $210 which is the answer.
15% more of 40% is 46% so the sum is 86%, the remaining percentage then is 14%(1500) = 220

It’s a poorly worded question because heating and electricity are utilities, so you could take this as a trick question, but the choices lead you to know it’s a poorly worded question with no intent of trickery just stupidity
13:29 Again, another error? Someone please correct me if I'm wrong?🙏🏾
The pattern is clear;
Add the first two digits(xx), then multiply(*) by the single digit;
(1+8) x 3 = 27
(1+2) x 4 = 12
(2+2) x 8 = 32
Therefore, the answer ideally should be:
(1+2) x 9 = 27 🤷🏽♂️ , not 36
I got the same. But, there is no answer from the choices means, you have to try something else. There is not international standard pattern.
(1 x 9) + (3 x 9). It was changed in the answer at 24:21

Using velocity = distance / time (ie. v = d / t)
How long(t) will Olivia walk to ensure that her distance-covered equals distance-covered of Kiara?🤔
We can also say: "how long(t) will both of them walk till their distance-covered become equal?"
The preceding statement reduces the unknowns to one variable, and this is 't'. 🤔 ?
See below:
distance-covered of olivia = distance-covered of kiara
ie.
vt - 4 = v * t (where 'vt - 4' is from 8 = (d + 4) / t)
8t - 4 = 5t
3t = 4
t = 4 / 3
t = 1.33333333 hrs
convert to minutes, you get appr. 80minutes.
So, they both have to walk for 80 minutes to be at same position

Question at 6:00 is calculated wrong as you mentioned 5 but calculated 3
i think the supposed answer is 8. what do you think guys?
@@garetemeh621 yes its 8
yes i was thinking the same, but in option "8" is not even a choice
@onlinetrainingforeveryone can you please respond to this
@OnlineTrainingforEveryone pls respond to this
John's total expenditure is $1500, outof which utilities is 40% means 1500*40/100=600 and Heat & electricity is 15% more than Utility bills i.e 600*15/100=90 and total Heat & electricity is 690, so expenditure on Utility & heat & electricity are 600+690=1290, so other expediture is 1500-1290=$210
thank you. I understood this method better.
For the question at 6:25, If the answer should be from the given options then it should be option B) 10 and instead of '5' in 3rd triangle it should be '3'.
=> (3*8) + (8*x) = 104
=> 24 + 8x = 104
=> x = (104 - 24)/8
=> x = 80/8
=> x = 10
Or if the numberings are correct in the 3rd triangle, then the options are not correct and there should be '8'.
=> (5*8) + (8*x) = 104
=> 40 + 8x = 104
=> x = (104 - 40)/8
=> x = 64/8
=> x = 8
Regarding the question if speeds is simpler.
Subtract one speed from the other.
8-5=3 mph (relative speed)
The problem is equivalent as one stoped and the other walking at 3mph. This new equivalent problem demands the time when they met.
So speed is displacement over time.
Displacement is 4 and speed is 3. So the time is 4/3 of hour that is 80 mins.
I honestly do not understand anything you said
@@crystalsports1331 Basic physics.
If I want to solve the problem of speeds you must first find the relative speed between the two persons. This is done by subtracting the speeds. 8-5=3. So 3 is the relative speed.
Then the problem becomes simpler. You will assume the person is 4 units of length ahead of you and still because you are moving in relation to her at 3mph.
The definition of speed is displacement over time. So time is displacement over speed. This gives the value 4/3 that is the time. When converting to mins we will get 80 mins.
@@dfcastro why you choose 4 as displacement?
@@mel4361 because she is 4 miles behind the one girl walking at 5mph
@@mel4361 I think it's actually distance speed = (distance/time). time = (distance)/(speed) distance apart is 4 and speed difference is 3 so 4/3
@19:00
When Olivia will catch up, Kiara and Oliva will have walked the same time t.
1- For Kiara, t = d/5 where d is the distance she will walk until Olivia catches up => d = 5t
2- For Olivia, t = (d+4) / 8 since she started 4 miles behind. => 8 t = d+4 => d = 8t - 4.
from 1 and 2 : 5t = 8t -4 => t = 4/3 in hours thus (60*4)/3 = 80 minutes.
Total spending = $1500 while 40% of it for utilities = 0.4 * $1500 = $600 and cost of heating and electricity is 15% higher than cost of utilities = $600 * 1.15 = $690 therefore the cost of other spending other than heating, electricity, and utilities = $1500 - $600 - $690 = $1500 - $1290 = $210
question at 5:25, utilities expense = 600, 15% increase equals 690. Electricity, heating and utilities expense equals 1290. Remaining amount is 210.
7:45 The right (8, 4, 3) left (2, 6, ?). the right side is decreasing and left side is increasing by the same amount, first 4 then 1. right side (8 - 4 = 4) (4 - 1 = 3), left side (2 + 4 = 6)(6 + 1 = 7) so the answer is 7.
the correct anwer will be 10, because for the right side we make {3+1=4} and 3+4 = 7 and 7+1=8 for the other side we make 2+4=6 and which mean that we add 4 only and after that we make 6+4= 10
Thank you for sharing this video. It’s very insightful. I have an observation :Question at 30:35 minutes has a typo. The left bottom number of the 3rd triangle should be 3
At 20:20 you can simplify this, does not matter how far Kiara walks, what matters is Olivia walks 3mph faster than Kiara and needs to catchup 4 miles so you know that is 4/3 hours which is 80 mins
Option D for the question @25:14
Every time the cell shifts( rotates) right by 1 cell.
For the triangle: @ 21:55
3+1=4
4+4=8
In reverse order:
2+4=6
6+1=7
The question for 22:42
18 * 3 = 27
12 * 4 = 12
22 * 8 = 32
12 * 9 = ? ( it should be 13 not 12 )
Answer for 12 * 9 = 27
Answer for 13 * 9 = 36
But all good! You are still Awesome!
Agree there is an error the correct answer is 27 not 36
Almost brake my brain here.
at 1:46 the cube question New Volume = 343, Old Volume 125. Change in volume = 218. Percentage increase should be = 218/125 x 100 = 174.4% ?

John spending
40% of utility =600

Electricity +heat=600*115%=690

In the exercise of calculate number 13*9=? Please correct the number at initial expresion because it says 12 instead of 13. Thank you
At 17:50 it would be simpler to calculate total rent by taking the increase of 260 multiplying by 4 to give the increase for remaining students and multiplying by original students i.e. 260*4*5 = 5200, no need to do all those steps
The answer to question at 6:25 is 8 not 10. Though 8 is not one of the choices. In answering the question, you had used 3 as the number at the bottom of the triangle instead of 5.
he f up there , totally. 8 is the answer 8+5 = 13 and 13 x 8 = 104
it made me doubt my very basic logic for a bit there! thanks for both of you confirming that my brain did not go bonkers! :D
PEDMAS is a new term for us Indians who went to school in 90s. We have been taught BODMAS (B= Brackets, O = Orders ie powers, indices or roots, D: Division, M: Multiplication, A: Addition, S: Subtraction.
In missing expression aswell, for 12*9 the answer should be 27 not 36 (unfortunately 27 option it self not there)
Can anyone tell me about crossover tests??? Please
I think that volume *change* percent (in Q2) is (343-125)/125 i.e. 174.4%
exactly it should be 174.4%
5:31
John's total monthly spending is $1500.
40% of his spending goes towards utilities:
Utilities = 40% of $1500 = $600
The amount he spends on heating and electricity is 15% higher than what he spends on utilities:
Heating and Electricity = $600 + 15% of $600
= $600 + $90
= $690
To find the amount John spends on things other than heating, electricity, and utilities, we subtract the amounts spent on utilities and heating/electricity from his total spending:
Other Expenses = Total Spending - Utilities - Heating and Electricity
= $1500 - $600 - $690
= $210
Therefore, John spends $210 on things other than heating, electricity, and utilities.
For 23:06 question, ended up landing in a wrong one though logic seems to be ok! (1+8)*3=27; (1+2)*4=12; (2+2)*8=32; (1+2)*9=27
Well done! Your participation in the challenge is valued, and your answer reflects your dedication. Best wishes for a successful job interview and assessment test. Keep up the great work and continue reaching for your goals!
For John, 40% expenditure in utility is 40/100 * 1500 = 600. He spends on heating and electricity 15% more than utility which is 115/100 * 600 = 690. The remaining is 1500 - (600 +690) = 210
For the second question, the left lower veritices on screen is 5 instead of 3
Third questins, figured out by sum of numbers which was consistently fast
Kiara time quesytion. T= D/S => (4+x)/8 = x/5, solving for x gives 6 and 2/3. Getting Time, T = (6 2/3)/5 = 1 and 1/3 hrs = 80 min
The problem in majority question I take about a minute or 30-50 sec, and the test requires 18 sec on average for each question. Rare questions I finish before the average 18 sec to give me time for the other questions
0.4 for utilities, for heating and Electricty 0.15 of 0.4 = 0.06 +0.4=0.46, 0.46+0.4=0.86, What John spends on other things 1.00 - 0.86= 0.14 of 1500 = 210
17;53 : have another way : 260 for each , mean : 260x4 = 1040 for 1 person , total rent : 5x1040 =5200
Explanation at 24:24
the problem indicated 12*9=?, but the solution they solve 13*9.
Just saying that's why the answer didn't much the choice if we solve it.
2:09 Technically, it is 174% not 274%. Does it matter? Yes, especially when you are computing financial data.
218 is the increase "by" --174%
343 is the increase "to" --274%
It is grammar, and is widely known in the industry. Please correct me.
13:30 The answer should be 27
The idea is to add the first two digits, then multiply the sum by the second operand (part)
so 1+8 = 9, 9 * 3 = 27;
1 + 2 = 3, 3 * 4 = 12;
2 + 2 = 4, 4 * 8 = 32;
lastly 1 + 2 = 3, 3 * 9 = 27 just like the first line.. which doesn't exist between the answers and not 36 as you chose...
Else please elaborate further.
Why confuse us with wrong answers?
He shared a different question and solved a different one at 23:05. Your answer isn't wrong, it's the question that is wrong. 😂
kunt cant make a good vid
The maths questions dont need to be answer exactly as implied on 2:02 and 4:33. You dont have the time for that. In this case you just need to know that 343/125 is a number that begins by 2XX (since 125 only divides into 343 two times) then you can discard all other answers. Same as 33 x 5. Tha correct answer is a number that ends with a XX5 (only 1 answers is a number ending in 5, which is 165). Usually, math questions with such little time require a quick calculation that aims at a single correct option, without knowing all the digits of the operation or the exact result.
for the pyramid problem we can solve it in 3ways 1st one is sum of left side numbers should be equal to right side which replace ? with 7 and 2nd way is some of opposite side of triangle should be equal like 8 from left and 2 from right their some is 10 and 4 from left and 6 from right the sum is 10 and it leaves us with 3 from left and ? from right which gives us 7.
sorry guys if im wrong.
at 7.19 the explaination doesn't seem correct. the number on the triangle at the bottom right is 5 and not 3.... the answer of the missing number should be 8 and not 10. (5+8)*8=104
I agree 💯

- Jone spend on thing other than heating, electricity and utilities is $210 it calculated by his spending on utilities (40%*1500= 600) / his spending on heating & electricity (600*15%=90+600=690) finally 1500-(690+600)= 210
I struggle to understand the shape questions on crossover test
5:20 answer is wrong. John's total monthly spending is
$I500 of 40% of his spendings goes
towards utilities. And the amount
that he spends on heating and
electricity is 15% higher than what he
spends on utilities.
Answer is =>
1. Total Monthly Spending: $1500
2. Utilities Spending: $1500 * 0.40 = $600
3. Additional Spending on Heating and Electricity: 15% * $600 = $90
4. Total Spending on Heating and Electricity: $600 + $90 = $690

Using BODMAS, the answer is still 12.
At 7:29, you say the answer for the value on the triangle is 10, but should it not be 8 (which is not in the options). (5 + 8) x 8 = 104
so the pattern question that ends at 24:29 . . . in which real life situation would you encounter such BS?
The question about John's spending at 5:24 is a red herring. At least in the US, heating and electricity are considered utilities so the question makes no sense.
For the expresion 12/2 (3-1) there is a rule when 12/2 * 2 where 2/2 is equal to 1, so 12 is faster to be defined

13 = (5 + ?)
13 - 5 = ?
? = 8

After student left earlier :
Case 1 : 1040 / 4 = 260
Case 2 : 3120 / 4 = 780
Case 3 : Obviously no need to check because this is lower than case 2 which will increase the amount
Case 4 : Same as Case 3
Answer should be A.5,200
12:28 An alternate answer could be BLOW..right?
At 23:00 question and answer are differ from each other.
@13:20 is is wrong rigt ??
At 24:20 I do not think this is a good example question as 27 is also a valid answer using a different pattern, no way a candidate taking the test can determine which pattern is correct:
(1+8)*3 = 27
(1+2)*4 = 12
(2+2)*8 =32
(1+2)*9 = 27
In triangle (8+5)*8= 104 is the right answer.

6:56 mark the answer is 8 since the bottom triangle number is 5
Most of the questions have something wrong with them. Like, in the triangles one There is written 5 instead of 3. In the 'can you calculate' one 12*9 is written instead of 13 and so on. No wonder we're getting the answers wrong
This is what i was thinking
We don't care about the cube's size length, when the size is increased by 40%, the volume is multiplied by 1.4³=2.744 that is a 174.4% increase.
an alternative solution to the first word problem (around 12:00) is BLOW
Awesome job, Chris! You’re absolutely correct. All the best and your job and the hiring assessment test!
timing 22:40 u have mentioned 12 x 9 instead of 13 x 9
10.2 how does 40% = 0.4 comes while multiplying with $1500 and 15% = 1.15 comes . Why there is difference in calculating %
At: 3:07 the formula is incorrect
If you add 274 percent to 125 then the value will be 467.5.
Which is incorrect.
Correct formula will be -
New volume - old volume
__________________________ x 100
Old volume
Answer will be 174 percent
Some are wrong question and wrong solution.
For the triangle question, the answer should be 7.

all this questions are easy if you can use a calculator but the orders of the test is not to use it!! so every little calculation can take a lot of time.
Thank you for watching and leaving a comment with your idea as well! Please check out my other video tutorials and let me know what you think about them

Please let me know if it was helpful and good luck in your journey!
Great contribution! Thanks a lot.
Thanks a lot for this. It helps to prepare. But... I have seen at least 3 errors in the presentation of the questions. You correct it later on when you develop the solution but it only creates confusion... But thanks anyway!
Hi @onlineTraining team, thanks for posting this video. Can you confirm if one can use calculator during the test?
No
How 1.4% came in second question? Can somebody explain? Thanks! 2:40
If you increase 100% by 40%, it becomes 140% & 140% can be written as 1.4 as it is 140/100
2nd questions answer is wrong. question said by how much % volume increased so it will be ((343-125)/125)*100.
Thanks for all the correct answers, so awesome ao praiseworthy.
