Question
'A' and 'B' started a business by investing Rs. '6x' and
Rs. '8x' respectively. Five months later, 'A' withdrew Rs. 100 from his investment whereas 'B' invested Rs. 500 more. If at the end of the year, profit share of 'A' was Rs. 11,000 out of total profit of Rs. 33,000, then find the initial investment of 'B'.Solution
ATQ, Ratio of profit shares of 'A' and 'B' at the end of the year = {(6x X 5) + (6x - 100) X 7} : {(8x X 5) + (8x + 500) X 7} = (30x + 42x - 700) : (40x + 56x + 3500) = (72x - 700) : (96x + 3500) Now, profit share of 'B' = 33000 - 11000 = Rs. 22,000 ATQ; [(72x - 700) / (96x + 3500)] = 11000 / 22000 So, investment of 'B' = 700 X 8 = Rs. 5,600
