The Cost price of 1 kg cashew nuts = Rs.700
Cost price of 50 g of cashew nut = (700*50)/1000 = 35
The selling price of 50 g cashew nuts = Rs.45
Profit = Selling Price -Cost price = 45-35 = 10
Profit % = Profit x 100/Cost price
Profit % = 10 x 100/35 = 28.57% profit
Hence, the answer is 28.57% profit
Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub.
