C Correct answer
Explanation

Let R be Raju's age at marriage. Present age = R + 8. Given R + 8 = (6/5)R. 8 = R/5, so R = 40. Raju's present age = 48. Sister was 10 years younger at marriage, so she was 30. Her present age = 30 + 8 = 38.

AI explanation

Let Raju's age at the time of his marriage be x years, making his present age x + 8. According to the given ratio, his present age is 6/5 times his age at marriage, so x + 8 = 6x/5. Solving this equation yields 5x + 40 = 6x, which means Raju was 40 years old at marriage and is currently 48. Since his sister was 10 years younger than him at his marriage, she was 30 then, making her present age 38.
