Question

Find the selling price of a chair whose cost price is Rs 750 and
gain 14%.​

Answer 1

Step-by-step explanation:

$Cost \: price \: of \: a \: chair = 750 \: Rs$

$Gain = 14$%

$Gain = Selling \: price - Cost \: price$

$Gain = Selling \: price - 750$

$\small\boxed{Gain\%=\frac{Gain}{Cost \: price} × 100}$

$14 = \frac{S.P. - 750}{750} × 100$

$\frac{14}{100} = \frac{S.P}{750} - 1$

$\frac{S.P.}{750} = \frac{114}{100}$

$\frac{S.P.}{750} = \frac{57}{50}$

$\frac{S.P.}{15} = 57$

$S.P. = 57 * 15$

$Selling \: price = 855 \: rupees$

${\pink{\underline{\underline{Solution}}}}$

S.P.=$\frac{100+14}{100}×750$

=$\frac{114}{100}×750$

=$\frac{57}{50}×750$

=$\frac{57×750}{50}$

=$57×15$

If there is loss,

Then cp=$\frac{sp×100}{100-loss\ percent}$

If there is profit,

Then cp=$\frac{sp×100}{100+profit\ percent}$

If there is loss,

Then sp=$\frac{100-loss\ percent}{100}×C.P.$

If there is profit,

Then sp=$\frac{100+profit\ percent}{100}×C.P.$
