The way I did it....

30,000 > 4,000 by what percent

30,000- 4,000 = 26,000

26,000 = x/100 (4000)

x= 650

So If the question read 30,000 is what percent of 4,000 would the answer than be 750%? I think this is where I went wrong.

Thanks,

yes, exactly, it's the "greater than" that we have to be careful with.

Agree.

rich: where did you get this question from? This is not a genuine trick they've used. This is just nonsense, trying to question reader's ability to understand the question correctly by playing game of nonobvious ambiguity.
