Question

Find profit percent or loss percent as the case may be, for each of the following.

C.P. = $Rs500$

S.P. = $Rs590$

Answer 1

Step 1:- To find profit or loss

Here, C.P. = $Rs500$

S.P. = $Rs590$

⇒ $S.P.>C.P.$ ⇒ There is a profit

$$\begin{gathered} Profit=S.P.-C.P. \\ =590-500 \\ =90Rs \end{gathered}$$

Step 2 :- To find Profit percent

$$\begin{gathered} Profit\%=\frac{Profit}{C.P.}\times 100 \\ =\frac{90}{500}\times 100 \\ =18\% \end{gathered}$$

Therefore, there is profit of $18\%$.
