D
Correct answer
Explanation
Sarita invested Rs. 50000 for 12 months, Neita invested Rs. 80000 for 6 months (since she joined 6 months late). Ratio of investments = 50000 × 12 : 80000 × 6 = 600000 : 480000 = 5 : 4. Sarita's share = (5/9) × 18000 = Rs. 10000. Profit is divided in proportion to capital invested × time.
