If 15 men can reap a field in 35 days, how many men are required to reap the same field in 21 days?
Q1. If 15 men can reap a field in 35 days, how many men are required to reap the same field in 21 days?
Answer: 25 men
Explanation: The work done is the same in both cases. So, the product of the number of men and the days should be equal. 15 * 35 = 21 * x, x = (15 * 35) / 21 = 25.
