Question

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

Answer 1

Answer

If 36 men can finish a piece of work in 25 days.

36 men will do 1/25 work in 1 day.

1 men will do

$\frac{1}{25 \times 36}$

work in 1 day.

15 men will do

$\frac{1 \times 15}{25 \times 36}$

work in 1 day.

No of days 15 men will take to do the work

$\frac{25 \times 36}{15} \\ = 5 \times 12 \\ = 60$

Therefore, 15 men will take 60 days to complete the work.

Answer 2

Answer:

15 men will take 60 days to complete the work

Step-by-step explanation:

Here it is given that 36 men can do a piece of work in 25 days

We have to find the number of days 15 men will take to do the same work

Let us assume the number of days to be x

We will use inverse proportion

number of days taken by 36 men = 25

number of days taken by 15 men = x

                         15x = 36 × 25

                          15x = 900

                              x = 900/15

                              x = 60
