To fill a tank, 25 buckets of water is 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?

A 10

B 35

C 62.5

D none of these

Solution

Correct Answer: Option C

Let the capacity of 1 bucket = x.

Then, the capacity of tank = 25x.

New capacity of bucket = 2x/5

Required number of buckets = 25x/(2x/5)

= 62.5
