Answer» Correct Answer - Option 4 : Rs. 20000 Formula Used: Savings = Salary – Expenditure Calculation: Let the man's monthly salary be x So, the initial savings = (20/100) × x = 0.2x Hence, the initial expenses= x – 0.2x = 0.8x If the expenses increased by 20%, the new expenses = [(100 + 20)/100] × 0.8x = 0.96x So, the relation for savings becomes: 800 = x – 0.96x ⇒ x = Rs.20000 ∴ The man's monthly salary is Rs.20,000

Answer» Correct Answer - Option 4 : Rs. 20000

Formula Used:

Savings = Salary – Expenditure

Calculation:

Let the man's monthly salary be x

So, the initial savings = (20/100) × x = 0.2x

Hence, the initial expenses= x – 0.2x = 0.8x

If the expenses increased by 20%, the new expenses = [(100 + 20)/100] × 0.8x = 0.96x

So, the relation for savings becomes:

800 = x – 0.96x

⇒ x = Rs.20000

∴ The man's monthly salary is Rs.20,000
