    Question

    ‘A’ and ‘B’ started a business by investing Rs.

    ‘y’ and Rs. ‘y + 300’, respectively. If 10 months later the ratio of profit shares of ‘A’ and ‘B’ was 3:4, respectively, then find the amount (initially) invested by ‘B’.
    A Rs.1,250 Correct Answer Incorrect Answer
    B Rs.1,800 Correct Answer Incorrect Answer
    C Rs.2,200 Correct Answer Incorrect Answer
    D Rs.1,200 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ; [(10 × y)/{(y + 300) × 10}] = (3/4) Or, (10y × 4) = 30 × (y + 300) Or, 40y = 30y + 9000 Or, 10y = 9000 So, y = 900 So, initial investment made by ‘B’ = 900 + 300 = Rs. 1,200
