Answer:
The original price of computer was <u>$1500</u>.

The price of a computer was $1,200 after applying a 20% discount.
Now, to get the original price of the computer.
Let the original price be .
As given discount is 20%.
So, the price after discount = $1200.
Thus, $1200 is 80% of the price of computer. (100% - 20% = 80%.)
So, $1200 is equivalent to 80%.
And, is equivalent to 100%.
Now, by using cross multiplication we get the original price of computer:
⇒
⇒
<em>Dividing both sides by 80 we get:</em>
⇒
Therefore, the original price of computer was $1500.
