To fill a tank, 20 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 one-fifth of its present ?
Choose the correct choice:
A) 100	B) 200	C) 300	D) 400	E) 500
Let the capacity of 1 bucket = x.   Then, the capacity of tank = 20x.   New capacity of bucket = 1/5 x   Therefore, Required number of buckets = (20x)/(1x/5)   = (20x) x 5/1x   = 100/1=
