  • Question
  • A can finish a work in 24 days, B in 9 days and C in 12 days. B and C start the work but are forced to leave after 3 days. The remaining work was done by A in:


  • Options
  • A. 5 days
  • B. 6 days
  • C. 10 days
  • D.
    10 1 days
    2

  • Correct Answer
  • 10 days 

    Explanation

    (B + C)'s 1 day's work = 1 + 1 = 7 .
    9 12 36

    Work done by B and C in 3 days = 7 x 3 = 7 .
    36 12

    Remaining work = 1 - 7 = 5 .
    12 12

    Now, 1 work is done by A in 1 day.
    24

    So, 5 work is done by A in 24 x 5 = 10 days.
    12 12
