A Correct answer
Explanation

Let ages be 2x and 3x. (2x+3)/(3x+3) = 3/4. 8x + 12 = 9x + 9. x = 3. Amar's age is 2x = 6.

AI explanation

Let Amar's and Anjali's present ages be 2x and 3x. Three years hence, the ratio (2x + 3) / (3x + 3) equals 3 / 4. Cross-multiplying gives 8x + 12 = 9x + 9, so x = 3. Amar's present age is 2 times 3, which is 6 years.
