B Correct answer
Explanation

Ravi = 3x, Jai = 2x. Four years back, Ravi = 3x-4, Jai = 2x-4. Given (3x-4) = (2x-4) + 6. 3x-4 = 2x+2, so x=6. Jai's present age = 2x = 12.

AI explanation

Let the present ages of Ravi and Jai be 3x and 2x years. The current difference in their ages is 3x minus 2x, which equals x, and this age difference remains constant over time. Since Ravi was 6 years older than Jai four years ago, the current difference is x = 6. Jai's present age is 2x, which is 2 times 6, or 12 years.
