Question
The income of ‘X’ is 20% more than the income of
‘Y’. If the ratio of their expenditure is 5:4 and each saves Rs. 2000, then find the income of ‘Y’.Solution
Since X's income is 20% more than Y, let the income of ‘Y’ and ‘X’ be Rs. ‘5x’ and Rs. ‘6x’, respectively. According to the question, (6x – 2000) / (5x – 2000) = 5/4 Or, 24x – 8000 = 25x – 10000 Or, x = 2000 Income of ‘Y’ = 5x = 5 × 2000 = Rs. 10000
