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 bucket is reduced to two-fifth of its present ?
Let the capacity of 1 bucket = x.
Then, capacity of tank = 25x.
New capacity of bucket = (2/5)x
Required no of buckets = 25x/(2x/5) = 62.5
