B Correct answer
Explanation

Let Tenali's age be x, Ram's be 3x. (3x + 5) = 2.5 * (x + 5). 3x + 5 = 2.5x + 12.5. 0.5x = 7.5. x = 15.

AI explanation

Let Tenali's present age be t, making Ram's present age 3t. In five years, Tenali will be t + 5 and Ram will be 3t + 5, and the problem states that 3t + 5 equals 2.5 times t + 5. Multiplying the entire equation by 2 to clear the decimal gives 6t + 10 = 5t + 25, which simplifies to t = 15. Tenali is 15 years old.
