To fill a tank 25 buckets of water are required. How many buckets of water will be required to fill the same tank if the capacity of the bucket is reduced to two-fifth of its present capacity?

A) 30

B) 35

C) 62.5<

D) None of these

Explanation:

Let the capacity of 1 bucket = x.

Then, the capacity of the tank = 25x.

New capacity of bucket = (2/5)x

$\therefore$

Required no of buckets = 25x/(2x/5) = 62.5
