Question

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?

Answer 1

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.
