- After first day only 2/3rd remains. After second day only 3/4th of that remaining from 1st day evaporated. So, final answer = [x-((1/3)x+(2/3)*(3/4))]/x=1/6

- Assume that contents of the container is X
On the first day 1/3rd is evaporated.
(1 - 1/3) of X is remaining i.e. (2/3)X
On the Second day 3/4th is evaporated. Hence,
(1- 3/4) of (2/3)X is remaining
i.e. (1/4)(2/3)X = (1/6) X
Hence 1/6th of the contents of the container is remaining
