Question

Market price is 250rs, discount Percentage is 5%,then selling price=?​

Answer 1

Discount %$=\frac{Discount}{Marked \: price}×100$

$Discount=marked \: price-selling \: price$

Discount %$=\frac{M.P. - S.P.}{MP}×100$

$5 =\frac{250 - S.P.}{250}×100$

$\frac{5}{100}=(1 - \frac{S.P.}{250})$

$\frac{1}{20}=(1 - \frac{S.P.}{250})$

$\frac{S.P}{250}=(1 - \frac{1}{20})$

$\frac{S.P.}{250}=\frac{19}{20}$

$S.P. =\frac{19}{20} × 250$

$S.P. =\frac{19}{2} × 25$

$S.P. =\frac{475}{2}$

$Selling \: price=237.5 \: rupees$
