A Correct answer
Explanation

Krishnamurthy invested 6000 for 12 months. Madhavan invested 4000 for 9 months. Ratio of investment = (6000*12) : (4000*9) = 72000 : 36000 = 2:1. Madhavan's share = 1/3 * 5100 = 1700.

AI explanation

The profit ratio is determined by multiplying each partner's investment by the time it was active. Krishnamurthy invested Rs. 6000 for 12 months, giving a product of 72000, while Madhavan invested Rs. 4000 for 9 months, giving a product of 36000. The ratio of their shares is 72000 : 36000, which simplifies to 2 : 1. Since Madhavan holds 1 part out of the 3 total parts, his share is (1 / 3) * 5100, which is Rs. 1700.
