Answer 2

Given : The sale price of notebook is 36 with loss; if it would sale with 72 then the profit is amount twice of loss.

To Find : What is the cost price?​

Solution:

Let say cost price = C

Sale price = 36

Loss =   C - 36

Sale price = 72

Profit = 72  - C

Profit   = 2 ( Loss)

=> 72 - C  = 2 ( C - 36)

=> 72 - C = 2C - 72

=> 3C = 144

=> C = 48

Cost Price = 48
