Explanation

Call the original price x. That price is discounted by 15% to get 612:

$$0.85x = \612$$
$$x = \720$$

Do not add 15% of $612 to$612. The 15% figure is a percent of the unknown original number, not of $612. _________________ Sandy If you found this post useful, please let me know by pressing the Kudos Button Try our free Online GRE Test Manager Joined: 06 Jun 2018 Posts: 94 Followers: 2 Kudos [?]: 77 [0], given: 0 Re: After a 15% discount, the price of a computer was$612.

Actually we are looking for marked value of the computer.

Discounted price is basically 85% of marked price. it can be shown as follows:

(612 /85)*100

= 720.
