Answer 1

Answer:

rupees 1050 to gain 15%

Answer 2

$Given \: selling \:price \: of \: a\: T.V (s.p) = Rs \: 820$

$Loss (l ) = 10\%$

$Let \: cost \: price \:of \: the \: T.V = Rs \: x$

$c.p = \frac{s.p \times 100}{100-l }$

$= \frac{820 \times 100}{100-10}$

$= \frac{82000}{90}$

$= \frac{8200}{9} \: --(1)$

/* According to the problem given */

$If \: he \: wants \: Gain \: (g) = 15\%$

$New \: Selling \: price \: should \: be = c.p \Big(\frac{ 100+g}{100}\Big$

$= \frac{8200}{9}\times \Big( \frac{100+15}{100}\Big)$

$= \frac{8200}{9} \times \frac{115}{100}$

$= \frac{943000}{900}$

$= Rs \: 1047.78$

Therefore.,

$\red{ In \: order \: get \:15\% \:gain \: he \: should }$

$\red{ sell \:the \: T.V } \green { at \: Rs \: 1047.78 }$
