    C Rs.13200 Correct Answer Incorrect Answer
    D Rs.14500 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the income of ‘S’ be Rs. ‘x’ Therefore, income of ‘R’ = x + 3x = Rs. 4x Expenditure of ‘S’ = 3600/2 = Rs. 1800 According to the question, 4x – 3600 = 7 × (x – 1800) Or, 4x – 3600 = 7x – 12600 Or, 3x = 9000 Or, x = 3000 Therefore, income of ‘R’ = 4x = Rs. 12000
