Question

A person saves 40% of his monthly salary. If his monthly expenditure is Rs. 5400, then his monthly savings, in rupees is ____.

• A. 7200
• B. 3600
• C. 1800
• D. 2400
• E. None of These

Answer 1

The correct option is B

3600

Let the monthly salary be $x$.
Saving percentage $=40\%$
Then, expenditure percentage $=100\%-40\%=60\%$
$60\%ofx=5400$
$\frac{60}{100}x=5400$
$x=9000$
Monthly savings $=\frac{40}{100}\times 9000=3600$
