Prep Test 49 Section 1, second LG

Postby ahindoy » Sun Apr 24, 2011 1:19 am

In this game you are given the scenario where 5 pieces of mail (letter, magazine, postcard, survey, flyer) need to be distributed to 3 roommates (G, J, R). I cannot figure out the necessary deduction.
Rule 1-G does not receive letter or magazine
Rule 2- If Letter to R, then Postcard to J
Rule 3-Whoever receives the flyer also receives at least one other piece of mail

The way I set up my diagram was the pieces of mail across the top and the roommates off to the side forming a 3x5 grid

Can anyone please describe the deduction I am not seeing, I scored well on all the other games but failed miserably on this one.

There are lots of deductions. You're going to have to be more specific about what questions are tripping you up. That being said, I'll try to get you started.

First, a 3x5 grid is not a good setup in this game (and in most games) because, for instance, it doesn't lend itself easily representing rule 3.

A better setup, IMHO, is to make a chart with the roommates, G J R, and put under (or over) those labels the pieces of mail. When you find out a particular roommate gets the flier, you mark it with a slot (F __) so that you know another piece of mail has to go with it.

Games like this tend to require that you focus on the distribution of elements--how many letters go to each person. Here you have 5 pieces of mail going to 3 people. Thus, assuming everyone gets a piece of mail (I think I remember that being in the setup) at least one of them will get only 1 piece of mail. Either the mail goes out 2 2 1 or 3 1 1. (Notice in the 3 1 1 scenario, the guy with 3 has to have the flier.)
