Question

72 men can do a piece of work in 25 days. In how many days will 30 men do the sane work

Answer 1

Days required for 72 men to do the work = 25
Days required for a man to do the work = 72 * 25 = 1800
Days required for 30 men to do the work = 1800 ÷ 30 = 60

Therefore, 30 men will do the same work in 60 days.

Answer 2

Answer: 60 days

Step-by-step explanation:

Given, 72 men can do a piece of work in 25 days.

⇒ A work can be completed by 72 men in 25 days.

∴ Work completed by 1 man in 1 day = $\frac{1}{72 * 25}$

∴ Work completed by 30 men in 1 day = $\frac{30}{72 * 25}$  = $\frac{1}{60}$

∴ In 60 days , 30 men can complete the work.
