At a store, they cut the price 40% for a particular item. By what percent must the item be increased if you wanted to sell it at the original price?

Here's one more way.....for argument's sake let the original price be $100. Then, the new price is just$60

So to find the percent increase to raise this back to the original price we have

[100- 60]/60 x 100%  = 40/60 x 100%  = 2/3 x 100%  = about [66 + 2/3] %

You must multiply the original price with the 40%. After that, you add the orginal price with the answer you got after multiplying the original price with 40%.

If this wasn't the answer you were looking for... I don't know what to tell you.

lets work through this one - it is a good question.    Don't worry anon, this was a very tricky question.

Let the original price be $100. It makes no difference what you choose for the original price but most people with find it easier if you choose an easy number rather than a letter. alright we reduce this by 40% so the new price will be 100 - 40% of 100 =$60

so the question becomes   (where x% is the price increase)

60 + x% of 60 = $100 $$\\60+\frac{x}{100}*60=100\\\\ \frac{x}{100}*60=40\\\\ \frac{x}{100}=\frac{40}{60}\\\\ \frac{x}{100}=\frac{2}{3}\\\\ x=\frac{2}{3}\times 100\\\\ x=66\frac{2}{3}\\\\ So the price would have to increase by 66\;\frac{2}{3} \;\%$$ Melody Mar 1, 2015 #3 +92206 +5 Actually I turned this into a much harder looking question than necessary. again let the original price by$100

40% discount brings he price down to $60 now we need to add the$40 back on.

What percent of $60 is$40 ?

$$\frac{40}{60}\times 100=\;66\frac{2}{3}\%$$
