At a Yoga center, 60% of the members are men and 40% of the members are women. If the average age of the men is 55 years and the average age of the women is 45 years, then 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. 51.
Given that,
60% of the members are men and 40% of the members are women
Let the total number of members present in yoga center be 100
The number of men = 60 × 100/100 = 60
The number of women = 100 - 60 = 40
If the average age of the men is 55 years and the average age of the women is 45 years
According to the question,
Average = (60 × 55 + 40 × 45)/100 = (3300 + 1800)/100 = 51 years
