  1. A contractor undertook a work to complete in 60 days. But just after 20 days he observed that only 1/5th of the project work had been completed. To complete the work in time (i.e,In rest days) minimum how many workers he had to increase, if there were initially 75 workers were deployed for the task?
    1. 25
    2. 50
    3. 75
    4. can’t be determined
  1. Correct Option: C

    Work done = 1/5
    remaining work = 4/5
    ∴ 4 (20 x 75) = 40 x N
    N = 150
    Therefore 75 men should be increased.
