Question
Person A spends 40% more than what he saves. He
allocates 30% of his total spending to cover his rent expenses. If he pays Rs. 2100 as rent, what is his total income?Solution
Let the savings of ‘A’ be Rs. ‘x’ So, expenditure of ‘A’ = x × 1.4 = Rs. ‘1.4x’ Income of ‘A’ = x + 1.4x = Rs. ‘2.4x’ Amount spent on rent = 2100 ATQ; 1.4x × 0.3 = 2100 Or, 0.42x = 2100 So, x = 5000 So, income of ‘A’ = 5000 × 2.4 = Rs.12,000
