AI explanation

Let Radha's present age be R; based on the first condition, R = 2(R - 12) - 3. Solving this equation yields R = 2R - 24 - 3, which simplifies to R = 27. The ratio of Raj's present age to Radha's present age is 4 : 9, so Raj's age is (4/9) * 27 = 12 years. Raj's age after 5 years will be 12 + 5 = 17 years.
