A Correct answer
Explanation

Let R and S be current ages. (R-3) = 2(S-3) => R = 2S - 3. (R+2) = (S+2) + 20 => R = S + 20. Equating: 2S - 3 = S + 20 => S = 23.

AI explanation

Let Simran's present age be x and Rahul's present age be y. Three years ago, y - 3 = 2(x - 3), which simplifies to y = 2x - 3. Two years from now, y + 2 = (x + 2) + 20, which simplifies to y = x + 20. Equating the two expressions gives 2x - 3 = x + 20, so x = 23. Simran's present age is 23 years.
