Answer 2

Answer:

500 ruppees.

Step-by-step explanation:

Let the cost price be 'x'.

Selling price = 450

Loss occured = 10%

_____________________

sp = cp - cp * loss percent         Formula

_____________________

450 = x - x * 10 / 100

450 = x - x / 10

450 = 10x - x / 10

450 = 9x / 10

9x = 450 * 10

9x = 4500

x = 4500 / 9

x = 500 ruppees
