Explanation

One year ago, Laxman:Gopal = 3:5. Laxman's salary ratio (last year:present) = 4:5, Gopal's = 2:3. Let last year's salaries be 3x and 5x. Present salaries: Laxman = 3x × 5/4 = 15x/4, Gopal = 5x × 3/2 = 15x/2. Total present = 15x/4 + 15x/2 = 15x/4 + 30x/4 = 45x/4 = 4290. So 45x = 17160, x = 381.33. Gopal's present salary = 15x/2 = 15 × 381.33/2 = Rs. 2860 (approximately). Wait, let me verify: 4290 × 4/45 = 381.33, 15 × 381.33/2 = 2860. Yes, correct. There's a typo in option B (shows 2640 in Hindi but answer is B).
