Price of 26kg of rice for trader= 26*20= 520
Price of 30kg of rice for trader= 30*36= 1080
Total cost price of mixed rice [C.P.] = 1080+520= 1600
Total amount of mixture = 26+30 = 56
Selling price per kg = 30
Total selling price of mixture [S.P.]= 30*56 = 1680
Profit = S.P.- C.P. = 1680-1600 = 80
% profit = {profit/C.P.}*100
={80/1600}*100
=5%........Solution
