      Question

      The sum of the incomes of 'A' and 'B' is Rs. 45,000. If

      'A' spends 85% of his income while 'B' spends 70% of his income, then the savings of 'B' will be Rs. 5,400 more than that of 'A'. Find the income of 'A'.
      A Rs. 20,000 Correct Answer Incorrect Answer
      B Rs. 22,000 Correct Answer Incorrect Answer
      C Rs. 14,000 Correct Answer Incorrect Answer
      D Rs. 16,000 Correct Answer Incorrect Answer
      E Rs. 18,000 Correct Answer Incorrect Answer

      Solution

      Let the income of 'A' be Rs. 'x' Therefore, income of 'B' = Rs. (45000 - x) Savings of 'A' = 0.15 X x = Rs. '0.15x' Savings of 'B' = Rs. {0.30 X (45000 - x)} According to the question, 0.30 X (45000 - x) - 0.15x = 5400 Or, 13500 - 0.30x - 0.15x = 5400 Or, 0.45x = 8100 Or, x = 18000 Therefore, income of 'A' = Rs. 18,000
