Answer 2

Answer:

The 10 male or 6 female can complete the work in 14 days.

Step-by-step explanation:

It is given that 10 male or 12 female can complete a wok in 21 days. It means

10 Male = 12 Female

We have to find the time in which 10 male and 6 female can completer the same work together.

10 Male + 6 Female = 12 Female + 6 Female = 18 Female

It is given that 12 female can complete the same work in 21 days.

12 female = 21 days

Work done by 12 in 21 days is $12\times 21$ and the same work done by 18 in d days.

$12\times 21=18\times d$

Divide both sides by 18.

$d=\frac{12\times 21}{18}=14$

Therefore 10 male or 6 female can complete the work in 14 days.
