At a school building, there is an overhead tank. To fill this tank 50 buckets of water are required. Assume that the capacity of the bucket is reduced to two-fifth of the present. How many buckets of water are required to fill the same tank?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 125.
The capacity of the tank = 50 buckets of water
Let the capacity of 1 bucket = 1 unit
So, total capacity of the tank = 50 units
The capacity of the bucket is reduced to two-fifths of the present capacity.
Present capacity of a bucket = (2/5) × 1 = 0.4 unit
Now, the total bucket required = 50/0.4 = 125
Therefore, a total of 125 buckets of water are required to fill the same tank.
