Explanation

Rahul = 12. Brother = 11. Father = 4 * Brother = 44. Ratio of Rahul to Father = 12:44 = 3:11.

AI explanation

Rahul's age is given as 12 years, and his brother Harry's age is 11 years. The age of Rahul's father is 4 times Harry's age, which is calculated as 4 * 11 = 44 years. The ratio of Rahul's age to his father's age is therefore 12 : 44. Dividing both numbers by their greatest common divisor of 4 simplifies the ratio to 3 : 11.
