Question

If 56 men can do a piece of work in 42 days how many men will do it in 14days

Answer 1

56 men can do a piece of work in 42 days

⇒ 42 days = 56 men

Find the number of men needed to complete the work in 1 day:

42 days = 56 men

1 day = 56 x 42 = 2352 men

Find the number of men needed to complete the work in 14 days:

1 day = 2352 men

14 days = 2352 ÷ 14 = 168 men

Answer: 168 men are needed to complete the work in 14 days.

Answer 2

Given :

56 men can do a piece of work in 42 days .

how many men will do it in 14 days ?

Finding number of days by one man -

if 56 men = 42 days

= 56 x 42 = 2352 days.

1 man can do the same work in 2352 days.

Finding number of men if the work complete in 14 days-

if 1 man = 2352 days

= 2352 ÷ 14

= 168.

Hence : 168 men can complete the work in 14 days.
