Question

To fill a tank, 30 buckets of water is required. If the capacity of bucket is reduced to two-fifth then how many buckets of water will be required to fill the same tank?

Answer 1

Let the capacity of 1 bucket = x

Then,
​​​​​​capacity of tank = 30x

New capacity of bucket = (2/5)x=2x/5

Required no of buckets = 30x/(2x/5) = 150/2
=75
