A Correct answer
Explanation

At marriage, the couple's average age was 25, so their total was 50. After 8 years, each parent has aged 8 years, so their total age is 50 + 16 = 66. Adding the 3-year-old daughter, the total family age is 69, and the average of 3 people is 69 / 3 = 23.

AI explanation

The total age of the couple at marriage was 50 years, so 8 years later their combined age is 50 plus 16, or 66 years. Adding their 3-year old daughter gives a new total age of 69 years for the family. Dividing this total by 3 people gives an average age of 23 years.
