A saves 20% of his monthly salary. If his monthly expenditure is Rs. 6000, then his monthly savings is :

Answer: Option A

Let the salary = 100 units
Savings = 20%
Savings = 100 × $$\frac{20}{100}$$ = 20 units
Expenditure = (100 - 20) = 80 units
According to the question,
80 units = Rs. 6000
1 unit     = Rs. 75
Savings = 75 × 20 = Rs. 1500
