In a company, the ratio of men to the number of woman is 3:2. 40% of the men are under the age of 25. 10% of the women are under the age of 25. What percentage of all the people in the company are under the age of 25?

Percentage of all the people in the company are under the age of 25=x

We have to use the weighted average.

x = (Σwi * vi) / Σ wi

w₁=3

w₂=2

v₁=40%

v₂=10%

x=[3 (40%) + 2 (25%) ] / (3+2) = 34%

Solution: 34% of all people in the company are under the age of 25.
