  • Question
  • 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 two-fifth of its present?


  • Options
  • A. 10
  • B. 35
  • C. 62.5
  • D. Cannot be determined
  • E. None of these

  • Correct Answer
  • 62.5 

    Explanation
    Let the capacity of 1 bucket = x

    Then, the capacity of tank = 25x.

    New capacity of bucket = 2 x
    5

    ∴ Required number of buckets = 25x
    (2x/5)

    = ❨ 25x x 5
    2x

    = 125
    2

    = 62.5
