There is a tank where certain fluid is stored. The tank is full. There are five guys who take half of what is stored. The first guy takes half, the second takes half a remainder, and so on.

How much fluid in terms of the initial quantity will they take away?

It was from one of the old ones..could'nt understand the prob though..

(1/2)^5

Or,

first guy takes half, leaves half
second guy takes half a half (a quarter), leaves a quarter
third guy, en eighth
fourth guy a sixteenth
fifth guy, a thirty-second

Is it 31/32 ??

1/2 + 1/4 + 1/8 + 1/16 + 1/32 = 31/32
