Find the S.P. if
(i) M.P. = Rs 1300 and Discount = 10%
(ii) M.P. = Rs 500 and Discount = 15%
(i) We know that $\mathrm{SP}=\mathrm{MP}-D$ iscount
Discount $\%=\frac{\text { Discount }}{\text { MP }} \times 100$
Discount $=\frac{\text { Discount } \% \times \mathrm{MP}}{100}$
$=\frac{10 \times 1300}{100}$
So, SP $=$ Rs. $\left(1300-\left(\frac{10}{100} \times 1300\right)\right)$
$=1300-130$
$=$ Rs. 1170
(ii) We know that $\mathrm{SP}=\mathrm{MP}-D$ iscount
Discount $\%=\frac{\text { Discount }}{\text { MP }} \times 100$
Discount $=\frac{\text { Discount } \% \times \mathrm{MP}}{100}$
$=\frac{15 \times 500}{100}$
So, SP $=$ Rs. $\left(500-\left(\frac{15}{100} \times 500\right)\right)$
$=$ Rs. $(500-75)$
$=$ Rs. 425
