**Studying for the LSAT / Numerical Distribution Technique?**

« **on:**August 26, 2006, 02:45:14 PM »

Hey guys,

I was wondering if someone could explain how to systematically/efficiently figure out a numerical distribution- I tend to just stare at the paper and figure out which numbers I haven't used yet. Sometimes I can see the pattern, but at other times I often lose track of what I've already written, and what I have yet to figure out. If possible, could you explain to me how you'd figure the example below out step by step in your head? (Ex: start with the highest # on teh left, then decrease by 1, etc. etc.)

Below are two sets of variables, and the variables in the first set must be distributed amogn variables in the second set. Use the conditions to figure out the numerical distribution:

First set: 12 books

Second set: 4 shelves

Conditions: There must be an odd number of books on each shelf.

Just in case you want to check- here's the answer, but I would like to know how you got there step by step, and how you knew what to do next after each distribution/eliminating a possibility:

9-1-1-1

7-3-1-1

5-5-1-1

5-3-3-1

Thanks!

3-3-3-3
