Q. A and B started a joint firm. A's investment was thrice the investment of B and the period of his investment was two times the period of investment of B. If B got Rs. 4,000 as profit then their total profit is ?
✅ Correct Answer: (C)
Rs. 28,000
Explanation: Suppose B invested Rs. x for y months.
Then A's investment is Rs. 3x for 2y months.
Ratio of investment of A and B = 6xy : xy = 6 : 1.
Now B's share = Rs. 4,000
∴ A's share = Rs. 24, 000
Hence, Total profit = Rs. 28,000
Then A's investment is Rs. 3x for 2y months.
Ratio of investment of A and B = 6xy : xy = 6 : 1.
Now B's share = Rs. 4,000
∴ A's share = Rs. 24, 000
Hence, Total profit = Rs. 28,000
