Vipul was studying for his examinations and the lights went off. It was around 1:00 AM. He lighted two uniform candles of equal length but one thicker than the other. The thick candle is supposed to last six hours and the thin one two hours less. When he finally went to sleep, the thick candle was twice as long as the thin one.

For how long did Vipul study in candle light?

let the length of two candle be = x
and name thicker1= A and thinner1=B
A light for 6*60=3600min and b light for= 4*60=240min
length of a after n minute = x- n(x/3600)
length of b after n minute = x- n(x/2400)
so now after when n minute when he sleep--> length of a = 2(length of b)
x- n(x/3600) = 2(x- n(x/2400))
->1- n/3600 =2- 2n/2400)
=>n=180 min= 3 hr
