Correct Answer: 64 years


Solution : The average age of six brothers is 15 years.
Total age of six brothers = 15 × 6 = 90 years
Adding the age of their father, the new average becomes 15 + 7 = 22
Total age = 22 × 7 = 154 years
Father's age = 154 – 90 = 64 years
Hence, the correct answer is 64 years.
