please read the forum rules: read-before-you-post-general-verbal-folder-guidelines-t2718.html

you can't post problems in this folder without giving the ORIGINAL SOURCE of the problem -- i.e., the company or author that first produced the problem (not, for instance, a forum or other secondhand source on which it has previously been posted).
if you don't know the original source, then i'm sorry, but you can't post the problem here.
this applies to MGMAT problems as well -- there are over three thousand problems in our database, so we won't recognize all of them from memory.

we will delete this thread within a week if the original source of the problem is not posted. thanks.
