      B Rs. 9,600 Correct Answer Incorrect Answer
      C Rs. 12,000 Correct Answer Incorrect Answer
      D Rs. 6,000 Correct Answer Incorrect Answer

      Solution

      Let the income of 'A' be Rs. 'x' Therefore, income of 'B' = Rs. (x βˆ’ 2400) Difference between their savings
      = 0.75x βˆ’ 0.75(x βˆ’ 2400)
      = 0.75x βˆ’ 0.75x + 0.75 Γ— 2400
      = Rs. 1800 Therefore, income of 'C' = (1800 / 0.15) = Rs. 12,000
