The current age ratio of Akash to karan is 7:9, and the current age ratio of karan to Chetna is 3:5. If the average of their present ages is 62 years, determine the difference between the present ages of karan and Chetna.
ATQ, Let the present age of ‘Akash’ be ‘7a’ years So, present age of ‘karan’ = ‘9a’ years And, present age of ‘Chetna’ = (9a/3) × 5 = ‘15a’ years According to the question, 7a + 9a + 15a = 3 × 62 Or, 31a = 186 Or, a = 6 Required difference = 15a – 9a = 6a = 36 years
