Expert Answer
Marked price = CP + 30% CP = 1.3CP
Let the total number of good he has be x
Hence, he sells x/2 goods at 1.3CP; x/4 goods at a discount of 15% and remaining x/4 goods at a discount of 30%
So, SP after 15% discount = 1.3CP - 15% of 1.3CP = 1.105CP
SP after 30% discount = 1.3CP - 30% of 1.3CP = 0.91CP
So, total SP for all goods = x/2 * 1.3CP + x/4 *1.105CP + x/4 * 0.91CP = 1.15375x CP
Hence profit = SP - CP = 1.15375x CP - xCP = 0.15375xCP
Profit% = profit/CP *100
Profit % = 0.15375xCP /xCP *100 = 15.375%
