A Correct answer
Explanation

Let incomes be 17x and 12x. Expenditures are 5y and 3y. Savings: 17x-5y=9000 and 12x-3y=9000. Solving: 5y=17x-9000 and 3y=12x-9000, so (17x-9000)/5 = (12x-9000)/3. Cross-multiplying: 51x-27000=60x-45000, giving 9x=18000, x=2000. Mohit's income = 12×2000 = Rs. 24000. Option A is correct.
