αηsωεя:-

Ler cp of iron =100%

Loss= 4%

SP=96%

96%=312

1%=312/96

100%=(312/96)×100=325

CP=325

Now profit=364-325=39

Profit%=(39/325)×100=12%

Hope you appreciate it....

Answer 2

Step-by-step explanation:

$let \: cp \: be \: x. \\ sp = 312 \\ loss = 4\% \\ \\ = > x - (4\% \: of \: x) =312 \\ = > \frac{100}{100} x \: - \: \frac{4}{100}x = 312 \\ = > 96x = 31200 \\ = > x = 325 \\ \\ now \: cp = 325 \\ sp = 364 \\ so \: gain\% = \frac{(364 - 325)}{325} \times 100 = \frac{39}{325} \times 100 = 12 \\ \\ gain = 12\%$
