The hourglass one seems to be wrong😕
First we let the 7 minutes be over then we turn the big hourglass again with the sand of 7 minutes which passed then when all the sand falls down then it will be 7 monutes again. So 7+7= 14 .....not 15??😓
It is wrong .. you turn them both over and when the 7 minute one runs through you put the eggs in.
The 11 minute one has 4 minutes left so you let it run through and then turn it over again .. 4 + 11 = 15

@Monika Rawat where is the unit
lol so true
Extra point. And how how does the radius compare to the size of unobservable universe
At 3:08 and 3:39 all you have to do is draw a line across the “equal to”symbol.
That was my idea too. I don't even know what the solution was saying.
that is is what i thought first eheheheh

@@dbrown2264It's supposed to mean 10 minutes to 10 o'clock. They're comparing 9.50 to like the time 9:50
Still dont get it like how tf?
Last riddle was amazing
the last puzzle was wrong.....
check it in calculator
😘😘😘😘😘😍😍😍 math intelligences puzzle nice
It really got me... 😂
I made the one at 1:40 way more complicated than it needed to. I did the square root of (7-3)!(7-3)!, which would be the square root of 4! times 4! which would be 24.
But it has 2 sets of numbers
(7-3)! (7-3)! is 576
Mark Joshua Hernandez yes, that’s why I said “the *square root* of (7-3)!(7-3)!” which would be the square root of 576 which would be 24
mine was 7+3^0+7+3^2
Actually, you would get +/-24 b/c of sqrt rule.
When dividing by a fraction, it must be multiplied by an inverted fraction? This is false. You can just do the division and skip the multiplication. 3:27, that is not a line, it is a line segment. Same issue at 4:00. 4:17, 7 minutes + 7 minutes is 14 minutes, not 15 minutes. This test is ABSOLUTE JUNK!
Dude you can multiply just do reciprocal
They meant to say turn the 11 min hourglass over, not the 7. 4 + 11=15.
@@Hritviz7 Of course you can multiply, but you don't have to is my point. You can divide by a fraction. The easiest example to illustrate this is 1 / (1/2). You can easily see by inspection that there is a 2:1 ratio of the numerator to the denominator. Similarly, it should be obvious that 2 / (1/3) is a 6 to 1 ratio. No multiplication going on here. I am using ratios by visual inspection.
@@markscheuer8648 4:37 They misspelled hourglasses too (they have hourglases).
@@markscheuer8648 It doesn't matter what they meant to say, only what they showed here (which is wrong).
For 3:29 you could just draw a line through the equal sign to make an NOT EQUAL TO sign
Edit: same with 3:57
Editx2: no one pointed this out anyway but I noticed someone had a similar comment to mine written a year ago, I promise I thought of this myself
Lol I thought that too

I love you darling
Hourglass solution is wrong. You measured out 14 minutes. The answer is to run both glasses until the 7 is empty. There are now 4 minutes left in the 11. Start cooking now. When the 11 has run out the last 4 minutes, turn it over for 11 more. 4 +11 = 15.
8+8=91
I believe that any form of change is considered a change. You CHANGED it to a 180 degree angle.
THE FOURTH RIDDLE CAN ACTUALLY HAVE TOTAL SOLUTION WHICH IS
((7-3!)+7)*3
LOOOOOOOOOOOOOL
TOOK ME MUCH LOGER THEN 10 SECS TO FIND IT THO
BIG brain
Nice job using factorials.
Another answers to those draw a line, draw a line on those equal to symbol so that it becomes 'is not equal to'
3:04 you just skipped the answer
2:25 Crocodile can be too because it is the only one who can live on both land and water!!
I don't agree with the hour glass answer, but I did solve it a different way.
First of all....If 7 min of sand passed through the 11 minute hour glass and you flip it over, you're just going to get another 7 minutes. That comes out to 14 min, not 15.
My answer (IF you can quickly reset these things, it will work. Idk if you can quickly reset them or not. Never messed with one. But, here goes):
Start both timers at the same time. Don't start boiling the egg yet. Wait for the 7 min one to expire.
Once the 7 min one expires, start boiling the egg, leaving the 11 min one running. You will have 4 min left on the 11 min timer; I.e. 4 minutes of boiling time.
Once the 11 min one expires, quickly reset it (if you can, IDK!) and restart it.
After it expires, that will be 15 min.
WHY IS SO HARD?MY BRAIN IS LIKE A BOMB THINKING THE ANSWER.BUT I LEARN A LOT.
the egg timer is wrong 11min and 7 min egg timers start when the 7 min runs out start the egg when the 11 min finishes which is 4 mins flip it when its done 11 mins the egg has spent 15 mins. the videos solution has you flip the 11 min timer back over after 7 mins which means 7 + 7 = 14 mins
If it's only for 14 mins then just use 7 mins timer twice
But the question is 15 mins
I love the last question

It is very very very super👍👨❤️💋👨👏👏👏👏👏👏
8:04 just fill each to their halfway point. 2 1/2 + 1 1/2 = 4
Exactly my solution xD
5L + 3L = 8L,, 8L/2 = 4L. I mean just fill both jars exactly half. Add the little one in bigger one. That's it.
1:20 can also be √7*3*√7+3=24 =>7*3+3=24
Or: (7-3!+7)*3=24
5:02 we can make a pyramid with triangular base so 3 triangles will stand up and base is 4
at 1:50 it stopped being about math ...
2 + 2 is 4 - 1 is 3 quick maths
5:02 First turn both hourglass together when the smaller one get emptied(7mins). Then bigger one have 4 mins left quickly again turn the smaller hourglass so that when big one get emptied(4mins) the smaller one have 3 min left turn it again as its opposite side have 4 mins(total 7 mins. 3 mins one 1 side 2nd side 4 mins 7-3=4)(4mins)
So when the smaller one get emptied we have 7+4+4=15. I jope it helped.
That works too. Here'e the most efficient answer. You have to START the egg boiling when the 7-minute glass is done, because that means there are only 4-minutes left in the 11-minute glass. When the 4 minutes are done, then you flipp the 11-minute glass over. So 4 minutes left + 11 new minutes = 15 total minutes. You only need to flip the 11-minute glass once, instead of flipping the 7-minute glass twice.
In 3:10,it says add one line to make it fine....so i placed a \ line on = so it becomes unequal. Am i right?
Me too
The hourglass riddle has the wrong solution, what you did was measure 14 minutes.
No
Yeah, I can't stand these kind of puzzles cuz so many have such an abstract solution that they are nearly impossible to figure out with the MANY math operators you could use. Makes it even worse when the person posting puts up the wrong answer.
7mhg = 7 minute hour glass
11mhg = 11 minute hour glass
Actual answer to hourglass : Flip both, when 7mhg is finished flip it over while letting 11mhg continue dropping the 4 minutes worth of sand left in it, when 11mhg is finished 7mhg should have dropped 4 minutes worth of sand back into original end while you are currently at 11 minutes, flip 7mhg over to drop the 4 minutes worth of sand into other end. When it is finished you have reached 15 minutes.
2 X 11 - 7 = 15
Turn over both hourglasses at the same time
When the 7-minute hourglass is done, drop your egg in
When the 11-minute hourglass is done, turn it over
When the 11-minute hourglass is done again, your egg has boiled for 15 minutes.
HOWEVER, a normal egg is already nuked after about 10 minutes.
@@seansantiagox thanks a lot, i was this close to thinking i was dumb lol
that's what i thought,he just measured 7 minutes twice...i think the answer is to start both at the same time...when the 7 is complete,turn it over...when the 11 is complete,turrn over the 7,and when the sand runs out,that is 15 minutes
How is the first even a riddle, it's the easiest one yet for some reason people are stupid, they think dividing by 2 is the same as 1/2
Coin Roll Hunting and Basketball
lol I always thought thirty divided by 1/2 was 15, until I learned it’s sixty.
watch my useful maths videos.
I think the issue was the 7 seconds that panicked people
i love how you think that knowing when twitter and facebook was founded is considered math.
your solution of the hourglass is wrong.
1. start 11min hourglass and 7min hourglass
2. turn 7 min hourglass after sand ends in 7min hourglass
3. when 11min hourglass ends then turn 7min glass again
Another way for 3L and 5L question
1.fill the 3L and put it in 5L
2.again fill 3L and fill it in 5L(u have 1L in 3L jar)
3.now 5L jar is full,,, spill it and pour the 1L which was in 3L jar into that empty 5L jar
4.again fill the 3L jar and pour it in 5L jar
5. U got 4L in 5L jar
3:27 or you can just cross the equal sign
Or change it into a less than or equal to sign (

That's amazing
*Having a mental breakdown*
hourglass is wrong...the correct answer is to start both at the same time...when the 7 runs out of sand,turn it over...then,when the 11 runs out,turn over the 7 again,because there will be 4 minutes of sand dropped,and when that runs out,you have 15 minutes
The intro made me laugh
ruclips.net/video/iYAanG2fgKs/видео.html
yes
Your solution to hourglass Is so confusing and I think it is wrong please check that once
that's harder than i expected😂
The hour glass timer one is wrong... you make them both go for 7 minutes and then flip them both over, and once the big one is done the egg is done. But if you do that then there is only 14 minutes because 7 minutes worth of sand have travelled from top to bottom and then you use that same 7 minutes to count the remaining time... 7+7 equaled 14 when I did math.....

The hourglass puzzle 4:10 solution is wrong. Refer to some books rather than some videos which give you wrong information.
Solution: Let's say the 11 min glass as glass_1 and 7 min glass as glass_2. Now start both the glass together. After 7 mins, glass_2 will be empty and glass_1 (11 - 7 = 4) will contain 4 mins sand. Now throw off the glass_2 and start boiling the eggs. After glass_1 empties(which contained 4mins), turn it over again and keep it until it finishes (4 + 11 = 15 mins). That's how you can boil an egg in 15 mins.

Min glass problem 15 min boiled egg xplanation totally wrong
It shoud be
Start with both minglass
11 min and 7 min
Then after 7 min turn the 7 min glass
N continue with the 11 min glass. 11 hr glass has 4 minutes reamining
Start there with the 4 min remaining n 7 min glass.
Wen u finish the 4 min of 11 min glass u got 3 min reamaining in the 7 min glass u invert it again then u got 4 min
Which mean 7 +4 +4 but u explain totally wrong there
Start with both hourglasses
11___7
after 7 minutes:
4 ____0
turn the 7 minutes hourglass:
4____7
wait for the 11 min glass to empty:
0____3
11 minutes have now passed turn the 7 minutes hourglass again (while in a 3 minutes/4 minutes state):
0____4
Wait for the 7 minutes glass to empty to get the additional 4 minutes
0____0
11 minutes + 4 minutes = 15 minutes.
Your solution to the hourglass problem is clearly wrong
yes
the mathematical equation about how he or she solve it its
11-7= 4
then 4+11 it fifteen 15 equal
he start it at the same time 11:7
when he empty the 7 min one he start it again 4:0 to 4:7
he try to to empty the 11 min hourglass 4:7 to 0:3
then hourglass he start the 11 min hour glass 0:3 to 11:3
then the time ended at 11 more min
lets solve
11:7 - 7:7 = 4:0
4:0 + 0:7 = 4:7
4:7 - 4:4 = 0:3
0:3 + 11:0 = 11:3
you''ll get 7 min for the first empty
then you'll get 7 min for the other one
then another 4 min for the other one (11-7 is 4)
if we add it its 18 isn't that wrong
18 is not equal to 15
It shoud be
Start with both minglass
11 min and 7 min
Then after 7 min turn the 7 min glass
N continue with the 11 min glass. 11 hr glass has 4 minutes reamining
Start there with the 4 min remaining n 7 min glass.
Wen u finish the 4 min of 11 min glass u got 3 min reamaining in the 7 min glass u invert it again then u got 4 min
Which mean 7 +4 +4 but u explain totally wrong there
@@DaYai9 Yes, thanks for the correct solution - that one was bugging me. Although, if I can choose when to start boiling the egg, a very simple solution if to start both and use the 7 mins from one timer to create a 4 min timer with the other. Then, start boiling the egg and simply use the 4 min time - when done turn it over and use the full 11 minutes - presto - enjoy egg :)
Choose wisely, you have other option now! :P
@1:46 -- rotating and turning it upside down is changing it.
2:06 -- the alligator; it's the only aquatic animal in the bunch.
3:07 -- diagnol line through the =, making it "not equals"
3:39 -- same
4:05 -- the "hour" glass explanation is wrong. If you do it that way you will only boil the egg for 4 + 7 =11 minutes. What you need to do is turn over both glasses, and start the egg when the 7-minute glass runs out. When the 11-minute glass finishes, that's 4 minutes; then turn the 11 minute glass over again -- when it runs out that will be 4+11 = 15 minutes.
5:05 -- that's only one triangle and the number 4. -- It can be done, though.
5:47 -- no riddle there; simply move any crayon
Some of these (Declaration of Independence; King Richard; Twitter; etc.) aren't math puzzles.

Task with sand watches: start both watches at same time. Whenever 7 minutes fill up, turn it around, for anti-clockwise running. 11 minutes will still run, and 7 minutes watch will be 4 minutes in advance the moment 11 minutes watch end up filling to top. When bring 7 minutes watch to starter position once again => to let 4 min. in advance flow back to complete mass. When ever 7 minutes remaining mass will flow back to complete mass we are going to have: 11 + 4 = 15. Seems hard to find solution at first, but if time not ticking, It took me like 2-3 minutes to find the solution. Every person thinks within one's own pace. I do not tolerate ticking tasks because it's bullshit. Not the way people should be examinated most of time. It's not a algorithms for first aid!
Can anyone make me understand solution at 5:00?
Its wrong bro xD
Stupid
I think the answer in the video is wrong, the answer should be like this, start the big and small hourglass at the same time, and after 7 min, flip over the small hourglass, then after 4 minutes, as the big hourglass ends, flip over the small hourglass again till it end the 4 mins remaining.
Nikko Sidro Baluyot After waiting the first 7 minutes the small one is empty and the big one has 11-7= 4 minutes left. If you flip the small one as soon as it’s done and then wait the remaining 4 minutes of the bigger one it’ll be 7 + 4 minutes by. Then if you flip the small one after the bigger one was done it will be empty after 3 minutes because it was full when it was flipped and it’s been the last 4 minutes of the bigger hourglass so 7 - 4 = 3 so you still won’t know exactly when it’s been 15 minutes because 7 + 4 + 3 is still only 14 minutes. The riddle is just wrong there is no way to make these hourglasses work exactly I think.
@@vernie7882 there are two solutions for this riddle,first case - turn over both of the hourglasses and after 7 min start boiling eggs.At this time in the top of the11 min hourglass will be left sand for counting 4 min,after it finishes counting,turn it over again and after 11 min eggs will be ready(4+11=15).Second case -start boiling eggs,turn over both of the hourglasses, after 7 min turn over the 7 min hourglass,at this time there will be sand for counting 4 and 7 min in the 11 min and 7 min hourglasses respectively.After 4 min in the 7 min hourglass will be left above sand for counting 3 min and bellow sand for counting 4 min,turn the 7 min hourglass over, after it finishes counting the eggs will be ready(11+4=15)

30/ 0.5 + 10 (since .5 is the decimal form of 1/2) .5 goes into 30 60 times. So now you have 60+10 and that equals 70 easy :)
Your soluion to the hourglass problem is wrong because you did not state at what point you should start the egg boiling. Here is the solution:
Flip both hourglasses at the same time. When the 7-minute glass is DONE, that's when you start the egg boiling. There are now 4 minutes of sand left in the 11-minute hourglass. When those 4 minutes are up, flip the 11-mnute hourglass over again. The egg is done when the sand is finished in the 11-minute hourglass. Why? Because 4 minutes that were remaining when you started the egg boiling plus the 11 minutes when you flipped it the second time equals 15 minutes.

Also before I even look at the answer for the "Which one is the odd one out?" question; This question is also already wrong because each animal can be singled out as the odd one out.
A house cat amongst wild animals
A color changing animal amongst animals that can't change color,
A two legged hopping kangaroo amongst animals with 4 legs.
A cheetah, the fastest animal on earth.
An alligator, the arguably the strongest animal on earth which also spiny unlike the others. And yes that is an alligator not a crocodile. You can tell by the teeth.
A camel has a hump
These riddles are bad!
the hourglass solution you gave us is wrong
the mathematical equation about how you solve it is
11-7= 4
then 4+11 it fifteen 15 is equal
to 15
but whenever i look at it its wrong
he start it at the same time 11:7
when he empty the 7 min one he start it again 4:0 to 4:7
he try to to empty the 11 min hourglass 4:7 to 0:3
then hourglass he start the 11 min hour glass 0:3 to 11:3
then the time ended at 11 more min
lets solve
11:7 - 7:7 = 4:0
4:0 + 0:7 = 4:7
4:7 - 4:4 = 0:3
0:3 + 11:0 = 11:3
you''ll get 7 min for the first empty
then you'll get 7 min for the other one
then another 4 min for the other one (11-7 is 4)
if we add it its 18 isn't that wrong
18 is not equal to 15
Add one line to make it fine - I just crossed out the equal sign!
4:45 should say "DON'T turn over the big hourglass. Only turn over the smaller one. When the big one runs out (after 4 minutes), turn over the small one. When it finishes it will have been 15 minutes."
I was scratching my head with the suggestion of flipping over the 11-minute timer at the 7 minute mark, which would mean it would finish after 7 more minites had gone by. I kept coming up with 14 minutes. Then I realized the mistake (as stated above).
You are wrong in that case it will be 18min
@@wolframalpha8634 No it won't. If you turn the small one over as soon as it finishes once, then wait until the big one finishes, four minutes worth of sand will be at the bottom of the small timer. So as soon as the big timer finishes, you flip the small timer BACK over. Once those four-minutes worth of sand have passed through, exactly 15 minutes will have transpired.
(7+4+4=15)
😁
@@sw386 if the 11min timer and 7min timer start together as soon as the 7min timer gets completed won't 4 min worth of sand be in the 11min timer??when exactly the 7min timer gets completed we need to turn it over again ..now when the 4min worth sand in 11min timer gets over then 3 min worth sand would remain in 7min timer then the total time taken would be (11+3 = 14)
@@wolframalpha8634 Yes, that's why you turn it BACK over as soon as the 11 minite timer is finished. That way, the four minutes of sand thay have collected in the bottom of the small timer can be used to finish adding up to 15 minutes.
Small timer: 7 minutes---flip, 4 minutes (big timer finishes)---flip again, 4 minutes later, small timer runs out.
7+4+4=15
100% agree
It works both ways 👍
I think the first one is wrong because when you say divide 30 by half actually means you have to multiply and then add ten and if you get confused when it says half thirty by 2 then .you divide
3:05 where is the answer????
Yeah, where is it?
@EuniceDivine Reyes also because horse and pig relate, duck is a bird and water creature, eagle is bird and crocodile is water creature, so relate. Cobra is none
Eagle is the odd one out. Only one that starts with a vowel.
@ 05:15 you said "make 4 triangles" TRIANGLES" is plural BUTT you only made ONE. So much for YOUR Math.
5:24 you need 3 more! Why you say... It said 3 TriangleS not triangle... But its okay i liked it it was clever :)
learn various maths from my videos.
Why is something not correct correct?!? Don't teach the wrong thing, like common, 1+9+8 obviously equals 19!!!
18
i know, it for april fool

@@KabajiSenpai you suck
The hourglass one is wrong .. you need to turn over both and when the 7 minute one runs out you put the eggs in and let the 11 minute one finish (4 minutes) and then turn it over again (11 minutes) .. and 4 + 11 = 15
In which battle did Richars III die .. ''his last one''(ha ha) .. which was at Bosworth Field.
