Sir I got your point but where i feel not being on the same page is as follows
I think that -past 3 o'clock- refer as
Let's take a scenario when we say 5 minutes past 5 it means 5: 05, so here also applying the same concept -as many minutes past 3 o' clock- means 3: X ( let's suppose as many minutes be equals to -X- minutes) so that makes a difference because that in turn ends with an equation 10+5x=240
Let me expalian How
As said 50 minutes ago and we are not provided with any particular information that says anything like 50 minutes back also we are somewhat past 3 o' clock so i take a random reference point as 2 o' so till 3 it's 60 minutes past according to question suppose X minutes are passed as of current time so in such position we have 2 cases either the X >50 or X< 50 minutes so get to the time 50 minutes ago we subtract X from 50 ie -50-X-
If that comes to be negative value then surely the time that is referred to be 50 minutes ago was somewhat past 3 o' clock and if that's positive the definitely the time we are refering to is before 3 o' clock so we subtract this from 60 minutes as our reference is 2 o' clock so we come up with 60-(50-x)
Now it's the time if added with 4 times X will end up 6 o' clock
So 6 o' clock from our initial reference will be 4-60 minutes that is 240 minutes hence equating the equation we get 60-(50-X)+4-X=240
10+5X=240
X=46 minutes
And it varifies well with the question statement
Now we have our current time as 3: 46
So it's 134 minutes to 6 o' clock

I don't think its the beauty of the puzzle but it is confusion created by wrong format of sentence. Beauty is that there can be various correct answers according to how each person perceive the sentence. One can say with logic that 50 min ago if it was --- means the time in clock was 4 times as many min passed 3 O' clock. Now if min passed after 3: 00 is 60 min ie 1 hr then 4 times it is 4: 00 which is the time on clock after 1 hr. So beauty lies in various answers how one perceives it. Otherwise the so called correct answer given does not match with the grammer of the sentence and only to fool. If I know the answer I can bend the meaning of the sentence to reach to it.

I got to the correct answer but the question is completely wrong. It should read -If 50 minutes ago it was 4 times as many minutes after 3 o'clock as it is now to 6 o'clock then how many minutes to 6 o'clock is it now? -. What the original question is asking is that if 50 minutes ago it was 4 times as many (4-50) minutes past 3 o'clock then how many minutes to 6 o'clock is it now. That answer would be that it is now 6: 20 which is after 6 o'clock so technically it would then be 700 minutes to 6 o'clock (another 11 hours and 40 minutes away. So the confusing bit is the fact that the question is badly formulated.

It's quite easy to see that four times as many must refer to the 50 minutes and not to the minutes remaining until 6 o'clock. Just rephrase. -Fifty minutes ago if it was four times as many minutes past three o'clock, what time is it now? -
If the puzzle is presented as such, then there is no mention of 6 o'clock, and this would be okay. The puzzle means 50 minutes ago it was 200 minutes past 3, so now it's 250 minutes past 3, which is 7: 10, which is 650 minutes (10 minutes shy of 11 hours) from the next time 6 o'clock shows up.

I think as many minutes in first statement is not related to final statement how many minutes?
So for this question we can have more than one answers.
Everything is same whatever u told except the last one where time from now to 6: 00 is X. We can take it Y. So we need to solve eqn 4-X+50+Y = 180 minutes where we can have infinitely many solutions for solving it.
One could be if X= 1 we can have Y= 126 min, in that case we will have Now timings as 3: 54 and 126 minutes are left to have 6 o clock.

I would suggest that there is an intrinsic ambiguity in the phrasing and that one may as reasonably construe the value sought (let us call it y) to be that number of minutes past 3: 00 such that fifty minutes ago is was four times as many minutes past 2: 00. Under this reading, y+10=4y, yielding the time of 3: 03: 20, whence one concludes that the time until 6: 00 will be 176: 40, or 176 complete minutes and change. Obviously, this is not so tidy a solution as you give, but it seems equally coherent to me.

Sorry late to the video. I think your answer is wrong for this reason. Your 4 times past three is 4: 44. The question references past 3 o-clock. I suggest that 50 minutes ago the time was 3: 36 as 4 - 36 is 144 mins plus the 36 mins is 180 mins. So the current time is 3: 36 plus 50 minutes which makes it 4: 26 or 94 minutes until 6 o-clock. It is saying that some time past three o-clock (x) it will be 4x minutes until 6 o-clock and that time was 50 minutes ago so how many minutes is it now until 6 o-clock.

Most of the viewers saying this. as bad question r grammatically wrong, honestly I think my english is even worst, but some how am able solved it with in 2, 3 minutes. there is nothing but remaining minutes to six to consider for calculation. Being Indians we are proud of Shakuntala Devi. Very soon a movie also going to come based on her life. I think this question is too small to judge her caliber.

The question was poor.
If she put -x- instead of -many minutes- then it will be ok.
The question doesn't shows that first part -many minutes- are same as second part -many minutes-.
Puzzle was very easy. No one can solve this puzzle because of that many minutes. And this is not confusion. This is totally wrong, no one can understand that two separate -many minutes- were same.

104 minutes, I took it like that 50 minutes ago, if it was four times as many minutes past three o' clock for 6, then tell me from now how many minutes will be remaining for 6'o clock?
I took it like that because when two phrases are repeated then u can omit one phrase assuming that it can be inferred from the meaning of sentence.

This puzzle is not tricky, but rather not worded correctly at all. As such, the answer provided is wrong. The statement can and SHOULD have been interpreted as 4x the value of 50. If this were on an actual math test, anybody answering anything other than 650 minutes would have failed the question.

Ammar. This puzzle is asked or worded incorrectly. It should have been clearly mentioned that 50 minutes ago it was 4 times as many minutes past 3 as it is to 6 now. From the question worded as it was, this wasn't clear at all. Once that is clear, it's very easy to figure out the answer.

Well language may be tough or ambiguous but I was still able to understand and solve the problem.
Because there was no other interpretation of this puzzle, hence after reading 3 times I was able to understand the question and solve it within minute.

I thought 4 times of current min value. So I came up with below solution
Current time: 5: 10
50 mins ago = 4: 20
4 times current min value i. e 20 -4=80 mins, past 3: 00 --> 4: 20
how many to 6: 00 --> 50 mins as current time as 5: 10

Ambiguous question. Without providing the complete data, you phrase a question in the second part and ask us to derive the data from the second part. How should we treat it? Question or Data? It is a simple puzzle buy for the ambiguity.

-If 50 minutes ago it was four times as many minutes past three o'clock than it is now to 6 o'clock, then how many minutes is it now to 6 o'clock? - That would be a proper way to phrase the question your version is just an unitelligable mess!

Your answer is wrong: 50 minutes ago if it was 4 times 50 (as many minutes) past 3 o clock. As in its 4-50 +50 mins past 3 o clcok = 7: 10 right now. So its 70 mins from 6 o clock backward or 650 mins forward to 6 o clock

I believe the question has grammatical issues and the question should have been
-Fifty minutes ago if there were 4 times as many minutes past 3 o'clock as it is to 6 o'clock, how much time is left to 6 o'clock-

I took it differently. Four times as many minutes means four times the current minutes. For example if the current time is 05: 23 then 4-23
