The price of an article was cut 20% for a sale. By what percent must the item be increased to again sell the article at the original price?

A 15%

B 20%

C 25%

D 30%

Correct Answer: Option C

25% Example: A $1.00 item reduced 20% will sell for 80cent. To sell it at $1 .00 again, you must increase the price 20%. 20cent is 25% of 80cent.
