    C 6520 Correct Answer Incorrect Answer
    D 5250 Correct Answer Incorrect Answer
    E 3365 Correct Answer Incorrect Answer

    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
