Question
'A' and 'B' began a business with investments of Rs.
8,000 and Rs. 15,500, respectively. After five months, 'A' increased his investment by 50%, while 'B' reduced his investment by Rs. 3,100. At the end of the year, the total profit earned by the business was Rs. 55,800. What is the profit share of 'A'?Solution
Ratio of profit shares of 'A' and 'B' at the end of the year = {8000 X 5 + (8000 X 7 X 1.5)}:{15500 X 5 + 12400 X 7} = {40000 + 84000}: {77500 + 86800} = 124000:164300 = 40:53 So, profit share of 'A' = 55800 X (40/93) = Rs. 24,000
