Question

60. If 36 men do a work in 25 days,
then in how many days will 15
men do it?
(1) 30
(2) 60
(3) 45
(4) 15​

Answer 1

Answer:

60 days

Step-by-step explanation:

Given, 36 men can finish a piece of work in 25 days

=> The number of man-days = 36*25 = 900

Let x be the number of days taken by the 15 men to do the piece of work

=> The number of man-days = 15x

But the number of man-days remains constant.

=> 15x = 900

x = 900/15 = 60

=> 15 men take 60 days to complete the piece of work.

Hope, it will help you
