Question
Income of 'A' is Rs. 2,000 more than that of 'B'. Both
spend 30% of their respective incomes. If the savings of 'C' is 20% of his income and is equal to the difference between the savings of 'A' and 'B', then find the income of 'C'.Solution
Let the income of 'A' be Rs. 'x' Therefore, income of 'B' = Rs. (x − 2000) Difference between their savings = 0.70x − 0.70(x − 2000)
= 0.70x − 0.70x + 0.70 × 2000
= Rs. 1400 Therefore, income of 'C' = (1400/0.20) = Rs. 7,000
