3. The digit in the hundreds place will be a 2, 4, or 6.
4. The digit in the tens place will be an odd number.

26 paychecks |
2009-01-21 |
|
From Kenneth:
Hello:
If someone is paid every two weeks, he receives 26 paychecks per year, (52 weeks/year)divided by (2 weeks/1 check) equals 26 paychecks per year.
However, if the calculation uses days instead of weeks, the answer is not exactly 26 paychecks. For example, 365 days divided by 14 days per paycheck
equals 26 1/14 paychecks. Fourteen days is equivalent to two weeks, isn't it?
Why is there this fractional amount of 1/14 of a paycheck?

The day of the week |
2006-03-19 |
|
From Neil:
A friend of mine has an excellent memory for dates and events that occurred on that date, but his party piece is the ability to tell you the day of the week that fell of any given date. This talent is all the more extraordinary because the answer comes back in less than 2 seconds (often under 1 second). By his own admission he is no mathematician.
Now his memory and knowledge are without question, but I challenged him that because of its diversity this party piece could not be based upon memory, but on mathematics. I believe that with the correct mathematical approach and the use of a common algorithm, anyone with a basic mathematical mind can do this in their head.
