Answer» Correct Answer - Option 1 : 4000 Given: Expenditure on medical = 15% of his income Expenditure on traveling = 25% of his income The expenditure left = Rs.2400 Calculation: Let the total income be 100% The left expenditure = 100% – (15% + 25%) ⇒ 100% – 40% ⇒ 60% Now, By using unitary method 60% = 2400 ⇒ 1% = 2400/60 ⇒ 1% = 40 ⇒ 100% = 100 × 40 ⇒ 100% = 4000 ∴ The total income of person will be Rs.4000 |
