Hi All,
The math behind this prompt can be done in a number of different ways (using fractions, decimals or ratios). The prompt is perfect for TESTing VALUES.
We're told that the original price of an item is increased by 25% and then THAT price is increased by 25%....
IF....
Starting value = $100
+ 25% = 100 + .25(100) = 125
+ 25% = 125 + .25(125) = 125 + 31.25 = 156.25
The question asks how the final price relates to the original price. This is essentially about Percentage Change, which means we should use the Percentage Change Formula:
Percentage Change = (New - Old)/Old = Difference/Original
Doing either calculation will yield the same result:
56.25/100 = 56.25%
Final Answer:
GMAT assassins aren't born, they're made,
Rich
