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.
