Question

18 men can reap a field in 35 days. For reaping the same field in 15 days, how many men are required?

Answer 1

Let number of men be ‘x’ men

Time (days)	35	15
No. of men	18	x

We know k = xy

35 × 18 = 15 × x

x = (35×18)/15

= 42

∴ 42 men are required to reap the same field in 15 days.
