Correct Answer - Option 3 :
Rs. 20,000
Given:
Monthly expenditure of man on food = 40%
Monthly expenditure of man on entertainment = 20%
Monthly expenditure of man on house rent = 10%
Monthly expenditure of man on travel = 15%
Monthly savings = Rs. 3,000
Formula Used:
Income = Total Expenditures + Savings
Percentage = (Value/Total value) × 100
Calculation:
Monthly salary of man = 100%
Total monthly expenditures = 40% + 20% + 10% + 15% = 85%
Monthly saving = 100% – 85% = 15%
⇒ 15 = (3,000/Monthly income) × 100
⇒ Monthly income = Rs. 20,000
∴ Monthly salary of man is Rs. 20,000.
