Question 149

If 20 women can lay a road of lengh 100 m in 10 days. 10 women can lay the same road of length 50m in:

Solution

Using, $$\frac{M_1D_1}{W_1}$$ $$=\frac{M_2D_2}{W_2}$$, where $$M$$ is number of men, $$D$$ is number of days and $$W$$ is work done.

According to ques,

=> $$\frac{20\times10}{100}=\frac{10\times D_2}{50}$$

=> $$2=\frac{D_2}{5}$$

=> $$D_2=2\times5=10$$ days

=> Ans - (B)
