Question

2. If 15 men can do a work in 12 days, how many men will do the same work in 6 days?​

Answer 1

Step-by-step explanation:

Let the total units of work to be done= 1

15 men 12 days work =1

15 men 1 day work = 1/12

1 man 1 day work = 1/(12*15)=1/180

10 men 1 day work = 10/180 = 1/18

so 10 men takes 18 days to complete the work

Answer 2

Answer:

30

Step-by-step explanation:

In 12 days 15 men can do the work

In 1 day 12*15 men can do the work

In 6 days 12*15/6 men can do the work

so, in 6 days 30 men can do the work
