C Correct answer
Explanation

Let ages be 14x and 17x. (14x+6)/(17x+6) = 17/20. 20(14x+6) = 17(17x+6). 280x + 120 = 289x + 102. 9x = 18, x = 2. Golu's age = 17 * 2 = 34.

AI explanation

Let the present ages of Vishal and Golu be 14x and 17x. After 6 years, their ages will be 14x plus 6 and 17x plus 6, giving the proportion 14x plus 6 divided by 17x plus 6 equals 17 over 20. Cross multiplying yields 280x plus 120 equals 289x plus 102, so 9x equals 18 and x equals 2. Golu's present age is 17 times 2, which is 34 years.
