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?
Options.
A) 61.5  B) 60.5  C) 63.5  D) 62.5  E) 64.5
Let capacity of 1 bucket = x   Capacity of the tank = 25x   New capacity of the bucket = 2x/5   Hence, number of buckets needed = 25x/(2x/5)=(25×5)/2=62.5   Answer is 62.5.
