      A Rs. 10,500 Correct Answer Incorrect Answer
      B Rs. 14,200 Correct Answer Incorrect Answer
      C Rs. 11,800 Correct Answer Incorrect Answer
      D Rs. 12,600 Correct Answer Incorrect Answer
      E Rs. 13,500 Correct Answer Incorrect Answer

      Solution

      Let the income of Abdul be Rs. '100y'. Savings of Abdul = 0.1 X 100y = Rs. 10y So, 10y = 4,000 Or, 'y' = 400 Income of Abdul = '100y' = 100 X 400 = Rs. 40,000 Amount received by wife from Abdul = (5/8) X 0.9 X 40,000 = Rs. 22,500 Amount received by son from Abdul = (2/8) X 0.9 X 40,000 = Rs. 9,000 Therefore, required amount = 9,000 + 0.2 X 22,500 = 9,000 + 4,500 = Rs. 13,500
