  • Options
  • A. 75
  • B. 92
  • C. 120
  • D. 110

  • Correct Answer
  • 110 

    Explanation

    Given in the question,
    Let k be the men there originally .
    Work done by y men can finish = 100 days
    If there were 10 men less, it would take more days finish the work in 10 days
    i.e. ( k - 10 ) = 110
    According to question ,
    k × 100 = ( k - 10 ) × 110
    ? 100k = 110k - 1100 ? 10k = 1100 ? k = 110
    Therefore , 110 men were there originally .
