Answer»
sp = 1536 \\ loss\% = 20 \: means \: he \: sell \: it \: at \: 80\% \\ cp = \frac{sp \times 100}{loss\%} \\ cp = \frac{1536 \times 100}{80} \\ cp = 1920 \\ new \: sp = 2040 \\ profit = sp - cp \\ p = 2040 - 1920 \\ p = 120 \\ p\% = \frac{p \times 100}{cp} \\ p\% = \frac{120 \times 100}{1920} \\ p\% = 6.25 \\ plse \: mark \: as \: brainliest
