C Correct answer
Explanation

Let Shyam's present age be x. Then Ram's present age is 2x. Ten years ago: Ram's age was 2x-10, Shyam's age was x-10. Given that Ram's age was four times Shyam's age: 2x-10 = 4(x-10). Solving: 2x-10 = 4x-40, giving -2x = -30, x = 15. Therefore Ram's present age = 2x = 30 years.
