12 men can finish a project in 20 days. 18 women can finish the same project in 16 days and 24 children can finish it in 18 days. 8 women and 16 children worked for 9 days and then left. In how many days will 10 men complete the remaining project

  • 10 1/2 days
  • 10 days
  • 9 days
  • 11 1/2 days
  • 9 1/2 days
  • Explanation:

    According to question,

    18×16W = 24×18B

    2W=3B

    8W+16B=28B

    BY M1D1/W1=M2D2/W2

    24×18/1=28×9/W2

    W2 = 7/12

    Remaining work = 1-7/12 = 5/12

    Remaining work will be done by 10 men.

    BY M1D1/W1=M2D2/W2

    12×20/11=10×D2÷5/12

    D2=10days
