Assume Total cost price of goods = Rs. 450
Our target SP of total goods = 120100×450=Rs.540
One-third of the goods costs = 450/3 = Rs.150
SP of one-third goods = 90100×150=Rs.135.
SP of the remaining goods = 540 – 135 = Rs. 405
CP of remaining (two-thirds) goods = Rs. 300
Hence, profit per cent = .105300×100=35%
