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 7/10 of its present?  Select the correct option:
A) 61.5 B) 60.5 C) 63.5 D) 35.71429 E) 64.5
Let capacity of 1 bucket = x   Capacity of the tank = 25x   New capacity of the bucket = 7x/10   Hence, number of buckets needed = 25x/(7x/10)=(25×10)/7=35.71429   Answer is 35.71429.
