      Income of Aman is Rs. 46,000. He spent (n - 6)% of

      income on food, (n + 4)% of income on rent, (2n - 5)% of income on transport and saves the remaining income. If his savings is Rs. 6,900, then find the amount spent by him on food.
      A Rs. 300n Correct Answer Incorrect Answer
      B Rs. 320n Correct Answer Incorrect Answer
      C Rs. 340n Correct Answer Incorrect Answer
      D Rs. 360n Correct Answer Incorrect Answer
      E Rs. 380n Correct Answer Incorrect Answer

      Solution

      Savings in percentage = (6900/46000) X 100 = 15% So, n - 6 + n + 4 + 2n - 5 = 100 - 15 Or, 4n - 7 = 85 Or, 4n = 92 Or, 'n' = 23 So, (n - 6) = 23 - 6 = 17 Therefore, amount spent by him on food = (0.17 x 46,000) ÷ 23 = Rs. 340n
