The average age of Ram and his two children is 17 years, and the average age of Ram’s wife and the same two children is 16 years. If Ram is 33 years old, what is the age of his wife?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 30 years
Both groups contain the same two children, so the difference of the two totals is the difference between Ram’s and his wife’s ages.
Total of Ram and the children \(=3\times17=51\) years
Total of the wife and the children \(=3\times16=48\) years
Ram is \(51-48=3\) years older than his wife
Wife’s age \(=33-3=30\) years
