16 men can do a piece of work in 10 days. How many men are needed to completed the work in 8 days?

  • Explanation

    According to the above given formula, If M1 persons can do W1 work in D1 days working T1 hours a day and M2 persons can do W2 work in D2 days working T2 hours a day then,

    M1D1W1= M2D2W2

    Here W1=W2

    16×10×1= 8×M2×1M2=16×10 ×18 ×1 =1608=20

    Hence, 20 men can complete the same work in 8 days

    Hence option C is correct
