The price of a suit that sells for $200 is reduced by 25%. by what percent must the price of the suit be increased to bring the price back to $200?

If the original price ($200) is reduced by 25%, then the sale price would be $150.

To bring the price back to $200, we must increase it by $50.

The question here is "what percentage increase is incurred if we go from $150 to $200 by adding $50?"

  $50
* 100% = 33.3%   (answer)
 $150
