Question

There are 3 friends Ritu, Shalu, and Aman. The age of Ritu is 2/5th of the age of Shalu while Aman is 12 years older than Ritu. The ratio of age of Shalu to Aman is 5 : 3. Find the age of Ritu after 4 years.

• A. 32 years
• B. 28 years
• C. 30 years
• D. 27 years

Answer 1

Answer:

B. 28 years

Let the Shalu age be 5x. Ritu age be 2/5 × 5x = 2x The age of Aman = 2x + 12 The ratio of age of Shalu to Aman is 5 : 3. ⇒ 5x/(2x + 12) = 5/3 ⇒ 3x = 2x + 12 ⇒ x = 12 The age of Ritu after 4 years = 2 × 12 + 4 = 28 years
