6 men and 9 women can complete a piece of work in 10 days what is the time taken by 4 men and 6 women to complete it

Answer»

Answer:

15 days

Step-by-step explanation:

let m is no of mens and w is no of womens

now 6 men and 9 women can do work in 10 days

6 men and 9 women 1 day work = 1/10

6m + 9W = 1/10

3(2m + 3w)= 1/10

2m + 3w = 1/30

now we REQUIRE work done by 4 men and 6 women

multiply 2 on both sides of above EQUATION

2(2m +3w) = 2/30

4m + 3w =1/15

4 men and 3 women 1 day work is 15 units

so, 4 men and 3 women can complete work in 15 days
