B Correct answer
Explanation

Let Ram's age be R and father's be F. F = 4R. (F+5) = 3(R+5). Substituting F: 4R + 5 = 3R + 15, so R = 10. Father's age F = 4 * 10 = 40.

AI explanation

Let Ram's present age be R years, making his father's present age 4R years. The future age equation states 4R + 5 = 3 times (R + 5). Expanding and solving gives 4R + 5 = 3R + 15, which means R = 10. Therefore, Ram's father's present age is 4 times 10, or 40 years.
