Best answer
Correct Answer - Option 4 : 10 days

Given

20 women lay road of length 100 m in 10 days

Concept used

M1D1/W1= M2D2/W2

Calculation

Here, M1 = 20

D1 = 10

W1 = 100

M2 = 10

D2 = X

W2 = 50

⇒ 20 × 10/100 = 10 × x/50

⇒ 2 × 50 = 10x

⇒ x = 10 days

∴ Then 10 women can lay the same road of length 50 m in 10 days
