D Correct answer
Explanation

Let the ages 10 years ago be 2x, 3x, and 4x. Their present ages are 2x+10, 3x+10, and 4x+10. The sum is 9x+30 = 93, so 9x = 63, x = 7. Paras's present age is 4(7)+10 = 38.

AI explanation

Ten years ago, the sum of their ages was 93 minus 30, which equals 63 years. Using the ratio 2:3:4, the age parts ten years ago were 14, 21, and 28 years. Adding 10 years to Paras's past age of 28 years gives a present age of 38 years.
