Correct answer
Explanation
Calculate profit shares using investment × time: A invests Rs. 4000 for 12 months = 48000; B invests Rs. 3000 for 8 months = 24000; C joins after 4 months with Rs. 2500 for 8 months = 20000. Ratio 48000:24000:20000 simplifies to 48:24:20 = 12:6:5. The claimed answer A (12:6:5) is correct.
