Explanation

Smita is 12 years younger than Varun, and after 4 years she'll be 25, so her present age is 21. Thus Varun's present age is 21 + 12 = 33. Gaurav:Varun = 3:11, so 3x = Gaurav and 11x = 33, giving x = 3. Gaurav's present age is 3×3 = 9. Last year Gaurav was 8, and his father Raghu was thrice that age (24), so Raghu's present age is 24 + 1 = 25.
