Pizza Discount | Feb. 22, 2010

The 10" pizza sells for \$2.99 at some pizza store. The store claims they have a great deal on the large 12" pizza, which is specially priced at \$ 3.66. What is the per cent discount the store is offering if any?

15% discount

Re: Pizza Discount | Feb. 22, 2010

10" pizza sells for \$2.99 => 2.99/10^2= \$(299/10000) per unit area.
12" pizza, priced at \$ 3.66 => 3.66/ 12^2 = \$(366/14400) per unit area.

the discount is given by
(299/10000)-(366/14400)/(366/14400) = (269/1794) * 100%

the answer is not exactly 15%

Re: Pizza Discount | Feb. 22, 2010

a little modification
[ (299/10000)-(366/14400) ]/(366/14400)

Just hope techgeek.in won't hate me ^0^

15% is definitely acceptable.

Thanks for the heads-up. I hadn't heard of these "offers" but now that I'm aware, I'll definitely stay away. Thanks again.
