Chocolate Maths

Nicked from Norma:


YOUR AGE BY CHOCOLATE MATH


DON'T CHEAT BY SCROLLING DOWN FIRST!

It takes less than a minute .



Work this out as you read .


1. First of all, pick the number of times a week that you would like to have chocolate (more than once but less than 10)




2. Multiply this number by 2 (just to be bold)




3. Add 5




4. Multiply it by 50 -- I'll wait while you get the calculator




5. If you have already had your birthday this year add 1759 ..
If you haven't, add 1758..




6... Now subtract the four digit year that you were born.





You should have a three digit number



The first digit of this was your original number
(i.e., how many times you want to have chocolate each week).





The next two numbers are ...........






YOUR AGE!

Fun one! I like little puzzles like that. Now I'll have to get on the phone with my niece (who has a master's degree in some kind of mathematics from UC Berkley) and she'll tell my why it works!
