AI explanation

The average age of the two sons five years ago was 12 years, so their total age five years ago was 24 years. This means their total present age is 24 + 2(5) = 34 years. Since the average age of the father and the two sons is 27 years, their combined present age is 27 * 3 = 81 years, making the father's present age 81 - 34 = 47 years.
