    Question

    profit would be used to fund a community project, and

    the remaining profit would be distributed according to their investment proportions. If the profit at the end of the year was Rs. 80000 and ‘Q’ received Rs. 20000, find the value of ‘s’.
    A 18 Correct Answer Incorrect Answer
    B 25 Correct Answer Incorrect Answer
    C 10 Correct Answer Incorrect Answer
    D 50 Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    Ratio of the investments of ‘P’, ‘Q’, and ‘R’ = 24000:28000:32000 = 3:3.5:4 = 6:7:8 (by multiplying each term by 2 to eliminate the decimal). Amount to be divided among them = Rs. {80000 × (100 - s)/100}. According to the question, {80000 × (100 - s)/100} × 7/21 = 20000, Or, 100 – s = 20000 × 100 × 21/7 × 1/80000, Or, 100 – s = 75, Or, s = 25.
