Solution : Given: The present ages of Vikas and Sujit are in the ratio of 5 : 4 ⇒ Present age of Vikas = 5 × A ⇒ Present age of Sujit = 4 × A Age of Vikas after 3 years = (5 × A) + 3 Age of Sujit after 3 years = (4 × A) + 3 The ratio of their ages after 3 years is 11 : 9 ⇒ $\frac{(5\times A)\:+\: 3}{(4\times A)\:+\: 3}=\frac{11}{9}$ ⇒ 9 × ((5 × A) + 3) = 11 × ((4 × A) + 3) ⇒ (45 × A) + 27 = (44 × A) + 33 ⇒ A = 6 years Therefore, Sujit's present age = 4 × A = 4 × 6 = 24 years.
Hence, the second option is correct.
