The average age of a family consisting of parents and a child five years ago was 27 years. Three years ago, the average age of parents was 41. The child was born ______ years ago.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e 8.
Five years ago: total age = 27 × 3 = 81
Now: 81 + 15 = 96
Three years ago: parents’ total = 41 × 2 = 82
Now: 82 + 6 = 88
Child’s present age = 96 − 88 = 8
