  • Options
  • A. 10 days
  • B. 18 days
  • C. 15 days
  • D. 12 days

  • Correct Answer
  • 15 days 

    Explanation

    According to the question,
    5 men's 1 day's work = 1/15 .....(i)
    ? 5 men's 5 day's work = (1/15) x 5 = 1/3
    ? Remaining work = 1 - (1/3) = 2/3
    5 men + 10 women can do 2/3 of the work in 5 days.
    ? 5 men + 10 women can do the whole of the work in 15/2 days.
    ? (5 men + 10 women's) 1 day's work = 2/15 .......(ii)
    10 women 1 days work = (2/15) - 5 men's 1 day's work
    = (2/15) - (1/15)
    = 1/15

    ? 10 women can finish the work in 15 days
