Question
Anoop invested Rs. 'r', while
Binny invested Rs. 15,000. After 7 months, Anoop reduced his investment by Rs. 3,000, and Binny reduced his investment by Rs. 5,000. If the profit share ratio of Binny to Anoop at the end of 21 months is 5:6, calculate 25% of 'r'.Solution
ATQ, Ratio of profit shares of 'Anoop' to that of 'Binny': = [r X 7 + (r - 3,000) X 14]:[15,000 X 7 + (15,000 - 5,000) X 14] = [r + (r - 3,000) X 2]:[15,000 + 10,000 X 2] = (3r - 6,000) :(35,000) So, (3r - 6,000) :(35,000) = 6:5 Or, 3r - 6,000 = 35000 X (6/5) Or, 3r - 6,000 = 42,000 Or, 3r = 48,000 So, 'r' = 16,000 Therefore, required value = 0.25 X 16,000 = 4,000
