Correct Answer: 54 years
Solution : Given, The average age of four brothers is 24 years ⇒ Total age of four brothers = 24 × 4 = 96 Now, their father is included and the average is increased by 6 years ⇒ New Average = 24 + 6 = 30 years ⇒ Total age of four brothers + Age of father = 30 × 5 = 150 ⇒ 96 + Age of father = 150 $\therefore$ Age of father = 150 – 96 = 54 years Hence, the correct answer is 54 years.
