Answer 2

$Cost \:price \:of \: a\: table \:lamp = Rs\:640$

$Profit (g) = 15\%$

$Let \: selling \:price (s.p) = Rs \:x$

$\boxed { \pink { s.p = c.p\Big( \frac{100+g}{100} \Big) }}$

$\implies x = 640 \Big( \frac{100+15}{100}\Big)$

$\implies x = 640 \Big( \frac{115}{100}\Big)$

$\implies x = Rs \: 736$

Therefore.,

$\red { Selling \:price \:of \:the \:table \:lamp}\\\green {= Rs \: 736}$
