Answer 1

Answer 2

$Original \:price \: of \:a \:Camera = Rs \: x$

$Discount \: Krishana \: get (d) = 20\%$

$Profit \: Krishna \: while \: selling \: the \\camera (g) = 40\%$

$Selling \:price \: of \: the \:camera \\= Original \:price \times \Big( \frac{100-d}{100} \Big)\Big( \frac{100+g}{100}\Big)$

$= x \times \frac{100-20}{100} \times \frac{100+40}{100} \\= x \times \frac{80}{100} \times \frac{140}{100}\\= 1.12x$

$Profit (g) = Selling \:price - Original \:price \\= 1.12x - x \\= 0.12x$

$Profit \: percentage = \frac{g}{original \:price} \times 100 \\= \frac{0.12x}{x} \times 100 \\= 0.12 \times 100 \\= 12\%$

Therefore.,

$\red { Profit \:earned \: by \: Krishna } \green {= 12\% }$
