A. $$\frac{{{\text{pr}}}}{{100}}$$
B. $$\frac{{{\text{r}}\left( {100 + {\text{p}}} \right)}}{{100}}$$
C. $$\frac{{{\text{p}}\left( {100 + {\text{r}}} \right)}}{{100}}$$
D. $$\frac{{{\text{p}}\left( {100 - {\text{r}}} \right)}}{{100}}$$
Answer: Option C
Solution (By Examveda Team)
$$\eqalign{ & {\text{C}}{\text{.P}}{\text{.}} = {\text{Rs}}{\text{. p}} \cr & {\text{Gain}} = {\text{r}}\% \cr & \therefore {\text{S}}{\text{.P}}{\text{.}} = {\text{q}} \cr & = \left( {100 + {\text{r}}} \right)\% {\text{ of Rs}}{\text{. p}} \cr & = \frac{{{\text{p}}\left( {100 + {\text{r}}} \right)}}{{100}} \cr} $$This Question Belongs to Arithmetic Ability >> Profit And Loss
