Explanation

Let Vivek's age at engagement be x. His present age (x+10) equals 5/3 of x, so x+10 = 5x/3. Solving: 3x+30 = 5x, so 2x = 30, x = 15. Vivek's present age = 25. Father's present age = 2×25 = 50. At engagement (10 years ago), father was 50−10 = 40. The question has grammatical errors ('her engagement' for 'his engagement') but the calculation leads to 40.
