Kusumtai bought 80 cookers at Rs. 700 each. Transport cost her Rs. 1280. If she wants a profit of Rs. 18000, what should be the selling price per cooker?
Cost price of 1 cooker =Rs. 700
∴ Cost price of 80 cookers =80×700=Rs. 56000
Money spent on transport =Rs. 1280
Total cost price = cost of 80 cookers + money spent on transport
=56000+1280
=Rs. 57280
Kusumtai wants a profit of Rs. 18000.
∴ Selling price of 80 cookers = Profit + Total cost price
=18000+57280
=Rs. 75280
∴ Selling price of 1 cooker =75280÷80=Rs. 941
Hence, Kusumtai should sell every cooker for Rs. 941.
