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

    ‘z’ and Rs. ‘z + 150’, respectively. If 6 months later the ratio of profit shares of ‘A’ and ‘B’ was 2:3, respectively, then find the amount (initially) invested by ‘B’.
    A Rs.250 Correct Answer Incorrect Answer
    B Rs.180 Correct Answer Incorrect Answer
    C Rs.220 Correct Answer Incorrect Answer
    D Rs.450 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ; [(6 × z)/{(z + 150) × 6}] = (2/3) Or, (6z × 3) = 12 × (z + 150) Or, 18z = 12z + 1800 Or, 6z = 1800 So, z = 300 So, initial investment made by ‘B’ = 300 + 150 = Rs. 450
