These questions are way easier than I could ever imagine. I would like to see some of the hardest samples. Thanks
decimals > fractions. The last question is easly expressed as 2.25 - 1.3 thanks for the content :)
2.25-1.333
@@discrete3511 2-25-1,32=0,93
same. I converted them to decimals first
for the 3rd question : she starts with 2*1/4 cup = 1/2 cup.
How could she possibly end with more milk than she started with ???? it has to be less than 1/2
Yeah it’s poorly written, they mean 2.25 cups and the start not 0.5 cups.
Ha ha ha. En effet cela ne fait pas très sérieux.
ça fait 5 min que je fronce les sourcils devant mon écran
I dont understand the second one, why proportion of 4/5=x/30?
If you do 10/15x100, you will probably get 66.666 don't worry if the number is greater than 4 after the point.. automatically number before d point will increase to by 1 so yeah its 67...thankyou
These are all good questions. Thank you for your time and guidance.
1st question answer- 4x = 30 , 5y =z as the output is same then 4x = 5y , now solve 5y = 30 , y=6
This is way too complicated, I did it with easier steps
Question 1: Multiply each price with 15% and see what is higher than 10$, so answer B. The answers are in the right order (lowest to highest) anyways.
Question 2: Divide 30 hours by 5 machines and you directly get 6 hours.
Question 3: Change the numbers in decimals, so you have 2.25 cups available for 0,67*2 = 1.34 cups of milk needed. Then subtract 2.25-1.34 and you have your answer 0.91, so answer C.
Idk why there are such complicated methods, maybe my simple logic wouldn't work for other questions and that's why? pls let me know since i'm planning on taking the test.
I agree master please teach me more Mathematic Questions
why do you divide 30 hours by 5 ?
You would fail the second question very fast
The complicated mind is better to figuring out more questions than having a one track mind.
Q1. If you had a large number of prices your method would be unsustainable
The questions in the exam can't possibly be that easy, right?
Im assuming these are the simplest. The SAT also has really simple questions that you could get right if you don’t study. But it’s also got some difficult questions not everyone can answer. I am assuming the GMAT is somewhat similar.
Additionally, these questions do require some knowledge. For example the first question could be answered simply by multiplying every possible answer by .15 and choosing the one that’s closest to 10 but he shows how to solve the question correctly, some people don’t know those little tricks and end up wasting too much time.
Some are. Some aren't
I literally did the thumbnail question in my head in 30 seconds. Wonder what the basis is for scholarships and if high enough test scores come into play.
@@baxoutthebox5682 how did you do this trick ?
i solved the questions within 6 sec, three of them. I don't know should I start prep for my GMAT. I have only 2 months to spend.
0:26assume cost of the sweater= XRs
given 15% discount on the cost of the sweater X which means X x 15/100 = 3X/20 he buys with X-3X/20
given in question that mel saved more than 10 so(X-3X/20) + 10 = X
17X+200/20=X ==>200/3=66.66
in question given more than 10 so if we put 11 in place of 10 then( X-3X/20)+11=X==>X=220/3=73.33 is coming then the answer could be C nearer to 75
thanks a lot, you have a very simple and nice way in explaning
Can't we do just: 10 :15 = x :100 -> 1000/15= 66.66 -> B. Calculation are more complicated but i am wondering if the logic is correct
The powers of estimation are good here. 15 goEs into 100 about 6.7 times. Multiply by the $10 savings and, Oh hey there’s the answer.
So out of curiosity... if I find these questions easy, what score range would I see myself in if I took the GMAT test right now
5:27 in question given total cup capacity is 2(1/4) =9/4 (total)
2batches of cookies for each batch cookie takes not 2/3 milk of total takes 2/3 milk similarly 2nd batch cookies takes 2/3 milk
2/3 + 2/3 = 2 x 2/3=4/3 milk used out of 9/4 milk ===> which means remaining would be 9/4-4/3=11/12 milk remaining out of 9/4
second one you just take 30 and multiply it by .8 (20% decrease) since you're increasing the machines by 20%
Thank you.
if you take if from the POV of the 4 machines working, it is an increase of 25%... You need to consider the 5 machines working as the basis of your assumptions to get the 20% "productivity boost"...
Can anybody tell me if the difficulty in this video correlates with the real GMAT?
Hi ! GMAT is an adaptive test meaning there is no specific difficulty level of the problems you'll get to see on the actual test. The more questions you answer correctly, higher gets the difficulty level of the next question. The questions discussed in the video do seem to be of moderate difficulty level
0:11 For the first problem, let X= price of the item and hence 15/100 x = 10 dollars hence x =1000/15 = 66.666 or 67 answer 2:09
2:18 For the second problem, I did it differently by assuming that the 30 machines have 30 items to complete, hence EACH machine will
complete 7.5/30 item per hour or 0.25 item per hour, hence 5 machines would (since they all work at the same rate ) complete 1.25 items per hour.
But since I assume (in the beginning ) that the work to be done is 30 items, then those 5 machines will complete the work (30 items) in 30/1.25 = 24 hours
but since the 4 machines did it in 30 hours (given), then the difference (30-24) is 6 answer 5:02
5:53. For the third and final problem, I break the 2 1/4 cups into 1 + 1 + 1/4 then after 2 (2/3) is removed it becomes 1/3 + 1/3 + 1/4 = 2/3 +1/4 =
8/12 + 3/12 = 11/12 . So answer = C (between 3/4 and 1)
thanks this is much easier to comprehend , I couldn't go around why I need to divided 15 n 10 by 5
@@ZahraAlWazzan it is the step to reduce the fraction for easier calculation
@@kamhayeat8806 why did you divide by 5?
preTEST teacher!!!!!!! awesome video!!
are sure these questions come in exam, because they are very easy and i'm also poor in maths but i can just solve them in my head.
Thanks for your question. I'm sure, they are similar questions to the official tests made available by accredited sources. By the way, congratulations on solving the questions just using mental math. =)
2:00 This seems overcomplicated, you can just take = (10/15) * 100 and you will get 67.
Seems overcomplicated, however I decided to explain the reason why we need to do the calculus in the way you mentioned. I believe if we understand the why, then we are more prepared to solve similar questions.
exactly
i actually did it myself this way before checking the solution in the video. I also noted the approach used in the video is long, yet time is of essence in these exam
3:37 four machine fills certain production in 30hours according to the question then asking how 5machines take time to fill the same production which means we can use the ratios concept 4 machines fills 30hours so 4 :30 and we dont the time consumed by the 5 machibes to fill so 5:x can be write as 4/5=30/x how could this vedio telling 4/5=x/30 ??
Please can anyone clarify this
it's a question of indirect variation
I solved these questions in my mind without writing anything on paper, is it necessary to show the solutions in GMAT test?🤔
Hey, it’s great!
I solve everything in a detailed way to put everyone in the same page. From people like you that can follow every step without a paper to those who need a little bit of more help.
In the gmat test you just need to mark the correct option. It’s not required to show your calculus.
@@OnezimoCardoso thank you sir ❤️
pretty awesome. love it.
Doesn't answer of first question should be 45 ?
It's says smallest amount the original price of the sweater that is nearest to orginal dollar which is 45 smallest than 66.66
Please I really want to learn how to solve math what do I do?
Very good
thanks a lot
you’r the man
My English failed at the second question. Please someone explain what is meant to be asked here. Only one machine or five machines? What does it by "fewer hours" mean? But it still asks for all the machines. Isn't it 6 hours very little for 5 machines when 4 could go by 30?
Fewer hour!! : Dumba$$ Let me explain, if you buy a cake for $10 but your friend bought the same cake for $6, then he paid $4 fewer money than you.
Here, in this question 5 machines took 6 hours less(i.e fewer hour) than the previous 30 hours. Hope you got it noob😎
4 tane makine eş zamanlı çalıştığında 30 saatte dolduruyorsa 5 makine aynı anda çalıştığında kaç saat az çalışıp aynı yeri doldurur diyor 5 makine 24 saat çalışır 30-24=6
freakin awesome
dude all you need to do for the first one is take 10/.15
I managed to do each question mentally in about 30 seconds. Would that make me much above average? (I'm aiming for above 700)
wow Mashallah !! can u do the test for me? lol
you are definitely above average.
How did it go?
@@KenyadianNurse for me I passed the gmat test from the company to hire me. I’m waiting for the interview.
How I can touch with you
@@heemoyemeni2220 Either by mouth or by hand wherever you feel comfortable, I guess 👍😐😖
Does the GMAT exam is required for Computer science student?
The second one made me laugh, how can be that easy
Hold on a second. Isn't the answer for Qsn 2 supposed to be 24?
I just did the calculation and x is 24. Makes sense since 5 machines reduce the work time.
the question says fewer hours, so 30-24=6
Just multiply 67*0.15
2 nd que
4 machines do it in 30 hours
How many hours will it take 5 machines to do it,
Divide 30 by 5
I guess that’s easier
is this seriously an exam meant for people over the age of 14?
6 fewer hours
100÷15×10=66.66 1:38
between 3/4 cup and 1 cup answer C

I don't understand how 2*1/4=9/4??? what kind of math is this?
Hey Bobby. That was not a product of the number 2 by the fraction 1/4 like you thought. In fact, 2 1/4 is a mixed number, that means 2 wholes and 1/4, and it is really equals 9/4 (improper fraction form) like I told and explained in the video. 👍
You can't read, there's no times sign

Hello hello~
Great content and subscribed! Would love hear what you think of our grad school channel. Thank you.
Chinese middle school level lol
This is too easy
Lol this one is Primary 3 math -_-
The questions can’t be that easy
