How does GMAT translate "increased by X%"? [#permalink] New post 20 Sep 2013, 10:40
I have been getting confused in how to convert the term "increased X%" into a formula.

Is "increased by X%" interpreted as:

\frac{100+X}{100}

OR

\frac{1+X}{100}

OR

1+X

Problem Example:
If the price increased by X% from 2001 to 2002 and by Y% from 2002 to 2003, what is the percentage increase from 2001 to 2003?

It's the second case.

The price in 2001 - p;
The price in 2002 - p*(1+\frac{x}{100}).

Consider this: say p = $100, and x=10%. So, the new price is 100(1 + 10/100) = 100*1.1 = 110.

Whenever we say , X% increase ....it means an increase of x per 100.

So result will be (100 + 100*(x/100)) or 100+X .

Increased by x% means increase by (1+x/100) times.

For example, if the original value is 100 and x=10%, then the final value is 100*(1+10/100)=110.
