Question:

If 16 men, working for 4 hrs per day for 8 days get 80/- then how many men required if the work is 6 hrs per day for 16 days they get 120/-?

Explanation:

Let the men required = x

We know that

Work = strength × time

∴ $\frac{m_{1} \times h_{1} \times t_{1}}{w_{1}} = \frac{m_{2} \times h_{2} \times t_{2}}{w_{2}}$

∵ Work ∝ wages

∴ $\frac{16 \times 4 \times 8}{80} = \frac{x \times 6 \times 16}{120}$

⇒ x = 8 men

Hence, option (d).
