Answer 1

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....

#ur Ans
________

Let the CP be X
sp = 312
loss% = 4

so

X*96/100 = 312

X = 312*100/96

X = 325

CP = 325

if we sold iron for 364
so
SP> CP there are profit

profit = SP -cp

profit = 364 -325 = 39

now

profit% = 39×100/325

Profit % = 12% Ans
