Hello everyone. Sorry about missing out on the "Math Puzzle of the Month of February 2012", but, anyways, this is the solution to the puzzle of January.

The last month on the calendar is July 2014.  If you look at it all of the titles are blue violet except for 28 titles.  This means all of them are of July except for 28 months.  In one year, 11 months would not be July.  How many times can 11 fit into 28?

28 / 11 = 2 R6

Okay. This means that so far, two years have passed.  The next month is January 2014.  Now we have to deal with the remainder of 6.  Well, six months other than July would go to June 2014.  But it doesn't end there.  It can also be July 2014 because there are six more months other than July.  Our two possibilities left are June 2014 and July 2014.  In order to settle it, we use the other set of information.  The other set says that all of the titles are blue except for 29 titles.  This means all of them are of August except for 29 months.  In one year, 11 months would not be August.  How many times can 11 fit into 29?

29 / 11 = 2 R7

Okay. Once again, this means so far that two years have passed.  The next month will be, as we already have discovered, January 2014.  Time for the final decision.  Is it June 2014 or July 2014?  The remainder determines it all.  There are seven months other than August, and that goes down to July 2014.

Here is the Math Puzzle of the Month of March 2012.

There are twelve tennis balls in front of you.  You are told to weigh them.  You can only use the scale three times.  You must figure out which tennis ball is the different one and if it is heavier or lighter than the others.

Overall job for you to do:  Discover how to do it.  There is a formula.

(Note:  Do not try weighing the tennis balls.  You do not know heavy each one is.  Just come up with the formula.)
