Correct Answer: 96
Solution : Let the present age of C be x years. Since 9 years ago, C celebrated his 5th birthday ⇒ x – 9 = 5 ⇒ x = 5 + 9 ⇒ x = 14 years So, C's present age is 14 years. Also, after 8 years, the B's age will be 4 times that of C's present age. So, B's present age is – ⇒ (14 × 4) – 8 = 56 – 8 = 48 Since A's present age is twice B's present age, A's present age is 48 × 2 = 96 years.
Hence, the second option is correct.
