Q. You are given two candles of equal size, which can burn 1 hour each. You have to measure 90 minutes with these candles. (There is no scale or clock). Also u r given a lighter.
Logical answer only! :P
-
I burn one candle and only quarter of the second.
-
When 1 candle burns completely = 1 hr ie 60 mins will be completed
left is 30 mins ie half of an hour
So let the next candle burn until it is half - completeling the next 30 mins
I hope it doesn't sound stupid :P
-
First light both of them and when both are burned half,turn one of them off. And when the first one is burned completely for 1 hour, burn the left half .
-
This tempted me. :P
Light one candle wholly => 60 mins
Light the second candle from both ends. Simple mathematics. ;)
-
oh! great all of you are correct!
i'll put up another
-

:-\
No scale... then how can one measure half? :P
-
Now, you have to measure 45 minutes with these candles.
alpha, can't you make out half of the candle? ::) :P
-
I burn one candle and only quarter of the second.
this answer is correct I guess for the 45 minutes , isn't it ? :-\

Wow! Nice twist! :D Witty answer!
No scale... then how can one measure half?
Visual estimation. ;D
But how can a candle have both ends? You'll have to cut a little bit of wax from the other end to get the wick. ::)

Can you measure, with accuracy? Try :P
-

Merci :D
I doubted it couldn't be simply 'half', too easy else. :P
Visual estimation. ;D

Don't candles usually have two ends?
-

but how you you figure out a quarter of a candle? [Without visual estimation]
-
Can you measure, with accuracy? Try :P
Ah, I think we are not measuring some kind of nuclear reaction here :P . So, 1-2 mins of error wouldn't matter! ::) :D
Merci

D' rien! :)

Umm... I don;t think so.. :-\ The candles here have a base, which is flat and the wick is not visible from outside. Maybe its different in other places too.
-

My answer was based on visual estimation ;)
good night everyone :D

Flat, yes... but it does have a wick at the bottom, so that the candle can be made to hold straight (without the help of a candle holder). ;)

Answer is 0. One of them is (s-s)

correct! "you guys know binomial right?" was only to confuse you.
another!
You're travelling to some village. At some point there is a fork in the road. You could go two ways but only one of them leads to the village. Lucky for you there are two men standing next to the fork. But unfortunately one of them always lies and one always speaks the truth and you do not know who is who. Since the men do not really like to help you, you are allowed to ask one of them only one question. Which question should you ask?
-

There is a boy who has exams and is not studying or losing focus on it because he is killing his precious time in a forum. There's an aunt who was gonna ban him out of it so that he goes back to his study, but there was a big hurdle, his msn- she has no control over that. Now, what should the guy do? :P
