Raju is currently 18 years older than Ravi after 6 years the ratio of their age will be 15 ∶ 12. How old is Raju’s age at present?
1. 86 years
2. 92 years
3. 76 years
4. 84 years 

Answer 1

Correct Answer - Option 4 : 84 years 

Given:

Raju currently 18 years older than Ravi

After 6 years the ratio of their age = 15: 12

Calculations:

Raju is currently 18 years older than Ravi

Difference between Raju and Ravi = 18 years

After 6 years’ age ratio of Raju and Ravi = 15 ∶ 12

Ratio of age difference = 15 – 12 = 3

⇒ 3 = 18

⇒ 1 = 6

Now, Raju's age after 6 years = 15 × 6 = 90

Raju's present age = 90 – 6 = 84 years

∴ The present age of Raju is 84 years
