that problem is in OG. thus we cannot discuss it here—unless it also appears in the FREE GMAT PREP software. ('i saw this problem discussed on the internet' does not change the copyright landscape.)
if this problem actually does appear in the FREE gmat prep software, please re-post your query with a screen shot from the software.
thanks.
