Question

3 men or 5 women or 8 children can do a work in 10 days. In how many days 2 men and 4 women and 8 children can do the work together?

Answer 1

Step-by-step explanation:

3 men or 5 women or 8 children can do a work in 10 days

3 men= 10 days

1 man = 10 × 3

1 man = 30 days ,2 men= 30/2

5 woman =10 days

1 woman = 10×5

1 woman = 50 days ,4 woman=50/4

8 children= 10 days

The work together done by 2 men and 4 woman and 8 children

2 men+ 4 woman + 8 children

30/2 + 50/4 + 10

150/4

42.5 days
