  • Question
  • 12 men complete a work in 9 days. After they have worked for 6 days, 4 more men join them. How many days will they take to complete the remaining work ?


  • Options
  • A. 2 days
  • B. 2.5 days
  • C. 2.25 days
  • D. 3 days

  • Correct Answer
  • 2.25 days 

    Explanation

    1 man's 1 day work = 1/108
    12 men's 6 day's work = 1/9 x 6 = 2/3

    Remaining work = 1 - 2/3 = 1/3

    16 men's 1 day work = 1/108 x 16 = 4/27
    4/27 work is done by them in 1 day.

    1/3 work is done by them in 27/4 x 1/3 = 9/4 days.
