Question

Peter made a net profit of 400 on selling a laptop and a printer. If Peter made a loss of 1200 on the printer, find the profit or loss made on selling the laptop.​

Answer 1

Answer:

Let the profit on laptop be x and that on printer be y

Peter made a net profit of 400 by selling both the printer and laptop.

∴ x + y = 400

Peter then sells the printer at a loss of 1200

∴ x- 1200 =400

∴ x = 1600

The profit made by Peter by selling the laptop is Rs 1600.

If we cross check the question which suggests that Peter made a net profit of 400 by selling the laptop and printer we get

Profit of laptop Rs 1600

Loss of printer Rs 1200

Profit of laptop - Loss of printer = Rs 1600- Rs 1200 = Rs 400

Net profit is Rs 400/-

Hope this helps.
