The ratio of age of Rohan and Sohna 5 years ago was 5 : 3 and the sum present age of both is 98 years. What is the age of Sohan 7 years hence?

Answer

Correct Answer : a ) 45 years

Explanation :

According to the question

Let the common multiple be x

The ratio of age of Rohan and Sohna 5 years ago was 5 : 3

⇒ Present age of Rohan = 5x + 5

Present age of Sohan = 3x + 5

⇒ Sum of present age of Both = 5x + 5 + 3x + 5

⇒ 8x + 10

⇒ 8x + 10 = 98

⇒ 8x = 98 – 10

⇒ 8x = 88

⇒ x = 11

Present age of Sohan = 3x + 5

⇒ 3 * 11 + 5

⇒ 33 + 5

⇒ 38 years

Age of sohan 7 years hence = 38 + 7

⇒ 45 years

Hence, (a) is the correct answer.
