Question

If 36 men can do a piece of work in 25 days, in how many days will 15 men do it?

Answer 1

Let the number of days required by men to do piece of work be ‘x’ days

Men	36	15
Time (days)	25	x

We know k = xy

36 × 25 = 15 × x

x = (36×25)/15

= 60

∴ 15 men require 60days to do a piece of work.
