Question
A and B started a business with initial investments of
Rs. 12000 and Rs. 28000 respectively. After one year, a profit of Rs. 8000 is earned. A being a working partner gets 25% of the profit for managing the business and rest of the profit is shared between them in the ratio of their investments. A invested his whole profit in a scheme offering 15% compound interest compounded annually. Find the interest earned by A after 2 years.Solution
The ratio of their investments = 12000:28000 = 3:7 Profit share of A for being a working partner = 0.25 times; 8000= Rs. 2000 Profit share of A for his investment = 3/10 times; 0.75 times; 8000 = Rs. 1800 Total profit of A = Rs. 1800 Compound interest earned by A = 3800{(1 + 0.15)2 ndash; 1} = Rs. 1225.5
