      Question

      The income of β€˜X’ is 20% more than the income of

      β€˜Y’. If the ratio of their expenditure is 5:4 and each saves Rs. 2000, then find the income of β€˜Y’.
      A Rs. 10000 Correct Answer Incorrect Answer
      B Rs. 12000 Correct Answer Incorrect Answer
      C Rs. 8000 Correct Answer Incorrect Answer
      D Rs. 15000 Correct Answer Incorrect Answer

      Solution

      Since X's income is 20% more than Y, let the income of β€˜Y’ and β€˜X’ be Rs. β€˜5x’ and Rs. β€˜6x’, respectively. According to the question, (6x – 2000) / (5x – 2000) = 5/4 Or, 24x – 8000 = 25x – 10000 Or, x = 2000 Income of β€˜Y’ = 5x = 5 Γ— 2000 = Rs. 10000
