Find discount in percent when

Question:

Find discount in percent when

(i) M.P. = Rs 900 and S.P. = Rs 873

(ii) M.P. = Rs 500 and S.P. = Rs 425

Solution:

(i) We know that $\mathrm{SP}=\mathrm{MP}-D$ iscount

So, $873=900-D$ iscount

Therefore, Discount $=$ Rs. $(900-873)$

$=$ Rs. 27

Discount $\%=\frac{\text { Discount }}{\text { MP }} \times 100 \%$

$=\frac{27}{900} \times 100 \%$

$=3 \%$

(ii) We know that SP $=\mathrm{MP}-D$ iscount

So, $425=500-D$ iscount

There fore, Discount $=$ Rs. $(500-425)$

$=\mathrm{Rs} .75$

Discount $\%=\frac{\text { Discount }}{\text { MP }} \times 100 \%$

$=\frac{75}{500} \times 100 \%$ $=15 \%$
