120 men consume 720 kg of rice in 30 days. In how many days can 90 men consume 270 kg?
We know that $$\dfrac{M_1 \times D_1}{W_1} = \dfrac{M_2 \times D_2}{W_2}$$ where M = No. of men, D = No. of days and W = Work
$$\dfrac{120 \times 30}{720} = \dfrac{90 \times D_2}{270}$$
=> $$D_2 = 15$$
Therefore, 90 men can consume 270 kg of rice in 15 days.
