100-10=90

450=90% of original find 100%
divide by 9

500=100%
origianl price=$500 (this is the hack way that only works with nice numbers)

Answer 2

Answer: Original Price=$450

Step-by-step explanation:

Price post discount=$450

Discount=10%

Let the original price be x

Given x - 10% of x=450

$x-\frac{10}{100}\times x$

$\frac{100x-10x}{100}$=450

$\frac{90x}{100}$=450

x=$\frac{100\times450}{90}$

On solving

x=500$

The original price =500$
