Show answer & explanation

Correct answer: C

Let the capacity of one bucket be x.

  1. Then the capacity of the tank = 25x.

  2. New capacity of one reduced bucket = (2/5) x.

  3. Number of such reduced buckets required = (25x) ÷ ((2/5) x).

  4. The x cancels, so this equals 25 ÷ (2/5) = 25 × (5/2) = 125/2 = 62.5.

Therefore the required number of buckets is 62.5.
