A and B enter into a business partnership where A contributes the entire capital of Rs. 50,000. B agrees to pay A interest at 10% per annum on half of the capital. A also works actively in the business and earns Rs. 1,500 monthly from the total profit. The remaining profit is divided equally between A and B. At the end of the year, A's total earnings are twice that of B's. What is the total profit earned during the year?

Explanation

A receives interest from B equal to 10% of half the capital, which is 10% of Rs. 25,000 = Rs. 2,500. A also earns Rs. 1,500 per month as a working partner, totaling Rs. 18,000 annually. Let the remaining profit share of A be P. Since the leftover profit is split equally, B's share is also P. Given that A's total income is double B's, we have: 2,500 + 18,000 + P = 2P, which simplifies to P = Rs. 20,500. Therefore, the total profit is the sum of both shares plus A's working partner remuneration: 2 * 20,500 + 18,000 = Rs. 59,000.
