After replacing an old member by a new member, it was found that the average age of five members of a club is the same as it was 3 years ago. The difference between the ages of the replaced and the new members is
-
- 2 years
- 4 years
- 8 years
- 15 years
- 2 years
Correct Option: D
According to question ,
Increase in ages of five members in 3 years = (3 × 5) years = 15 years
As average age remains same,
∴ Required difference = 15 years
