If 8 men can reap 40 hectares in 12 days, then how many hectares can 30 men reap in 20 days?
175 hectares
225 hectares
250 hectares
275 hectares
Explanation:
40 : x : : $\begin{cases}8 &: 30 ---(Men) \\12 &: 2 ---(Hectares) \end{cases}$
8 × 12 × x = 30 × 20 × 40
x = $\dfrac{30\times 20 \times 40}{8 \times 12}$ = 250 Hectares
