Question
The sum of the original incomes of βXβ and βYβ
is Rs. 60000. If the income of βXβ had been Rs. 6000 more, then it would have been 20% more than the original income of βYβ. βXβ and βYβ spend 80% and 75% of their respective original incomes. Find the difference between their savings.Solution
Let the original income of βXβ be Rs. x Therefore, original income of βYβ = Rs. (60000 β x) According to the question, (x + 6000) = 1.2(60000 β x) Or, x + 6000 = 72000 β 1.2x Or, 2.2x = 66000 Or, x = 30000 Income of βXβ = Rs. 30000
Income of βYβ = Rs. 30000 Savings of βXβ = 20% of 30000 = Rs. 6000
Savings of βYβ = 25% of 30000 = Rs. 7500 Required difference = Rs. 1500
