Please read the forum rules:
read-before-you-post-general-verbal-folder-guidelines-t2718.htmlYou 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 a forum or other secondhand source).
If you don't know the original source, then i'm sorry, but you can't post the problem here.
This rule applies to MGMAT problems as well. There are over three thousand problems in our database, so we can't possibly recognize all of them.
(This is also the wrong folder for MGMAT problems, which belong in the MGMAT CAT or MGMAT non-CAT folder.)
We'll have to kill this thread within a week if the original source of the problem is not posted.
Thanks.
