Please find attached the question.

I am more interested in the various ways people tackled/approached this question instead of the final answer.

Thanks.

I've seen this question before on this forum, and I've always thought it was a bit of a ridiculous question. We have information about estimates of income and population, but are the estimates accurate? We have no idea. I can't imagine seeing a real GMAT question worded in this way- instead, it would more likely say:

1) The population is greater than...
2) The total income is greater than...

Still, the answer is E regardless of the wording- you would need the upper limit on the population and the lower limit on total income to get the minimum possible per capita income (per capita income = total income/population).

Anyway, I'm curious about the source of the question.

thanks for the input Ian.

This question is actually written by GMAC. It comes from the GMATFocus Quant Diagnostic test which comes from GMAC. (www.gmatfocus.com).

Thanks, II. I haven't yet encountered the question in GMATFocus. A strange question!
