Question

Answer 1

Answer:

4 men and 9 women will complete same work in 24 days

Step-by-step explanation:

Given that 8 men or 12 women can complete work in 30 days

Thus, we have

8 men work = 12 women work

4 men work = 6 women work

Now, we have 4 men and 9 women

4 men + 9 women = 6 women + 9 women = 15 women

Also, given that 8 men or 12 women completes work in 30 days.

Let 15 women completes work in x days

Thus, we have

12 women × 30 days = 15 women × x days

x = (12 × 30)/15

x = 12 × 2

x = 24 days
