Question

Answer 1

Answer:47.04 days

Step-by-step explanation:

9 men + 15 women = 24 workers in 25 days then 39 men + 10 women =?

49:24::x:25

25x= 49x24

X=49x24/25

X= 47.04 days

Answer 2

Answer:

5 days

Step-by-step explanation:

9 men = 15 women ⇒ 3 men = 5 women ⇒ 6 men = 10 women

∴ 39 men + 10 women

   = 39 men + 6 men             ∵  10 women = 6 men

   = 45 men            ∵ it means 39 men and 10 women = 45 men

Now

9 men can complete in 25 days

1 men can complete in 25 * 9 days

45 men can complete in $\frac{( 25 * 9 )}{ 45}$  days  =  5 days
