Question:
A retailer buys a radio for Rs 225. His overhead expenses are Rs 15. If he sells the radio for Rs 300, determine his profit percent.
Solution:
Radio costs $=$ Rs. 225
Overhead expenses $=$ Rs. 15
C. $\mathrm{P}=$ Rs. $(225+15)=$ Rs. 240
S. $\mathrm{P}=$ Rs. 300
Profit $=$ SP $-$ CP
$=$ Rs. $(300-240)$
$=$ Rs. 60
Profit $\%=\frac{\text { Profit }}{\text { C.P }} \times 100$
$=\frac{60}{240} \times 100$
$=25 \%$
