At a health club, 56% of the members are women and 44% of the members are men. If the average age of the men is 35 years and the average age of the women is 30 years, what is the average age (in years) of all the members?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 32.2.
Average age = (Percentage of women × Age of women) + (Percentage of men × Age of men)
Average age = (0.56 × 30) + (0.44 × 35) = 16.8 + 15.4 = 32.2 years
