[FUN]: Math Trick


Choose a number between 2 and 9 inclusive!

1) Multiply by 2
2) Add 5
3) Multiply by 50
4) IF you already had your birthday this year, add 1760 ELSE add 1759.
5) Subtract the year you were born!
6) Check your result!

If your arithmetic is OK then you should have a three digit number! The first digit is the number you chose and the last two digits is your age!! Hope was fun for you!

Question: This works only for 2010. Can you suggest how this trick can adjusted in 2011 so that it does not fail? [comment to answer]
