Question

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?

Answer 1

10

One tank is 25 buckets of water, so 2/5 of a tank is 10 buckets of water.

Answer 2

62.5

Explanation:

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)

= 25x * 5/2x

= 125/2 = 62.5
