Your Age by Eating Out

This is amazing! Don't tell me your age; you probably would tell a falsehood anyway - but your waiter may know!

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 go out to eat.
(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

5. If you have already had your birthday this year add 1758...If you haven't, add 1757.

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 go out to restaurants in a week.)

The next two numbers are YOUR AGE !

This is the only year (2008) it will work, so spread it around while it lasts.

[Ed - Another one of the annoying silly calculations...as expected, it doesn't have anything to do with the number of times you eat out...

Let's see what goes on:

You are asked to select a digit except 0.

Then you multiply it by 100 (multiply by 2, and then multiply by 50) so that your age can be added to it without changing the numbers and making your original number the first digit.

You add 250 to the number (add 5, then multiply by 50) just to create confusion.

Then you add a number to this 250 to reach the current year - if you've had your birthday, this number is 1758 (2008-250)..otherwise it is 1757 (2008-250).

Now you add 250 to this number - basically reaching the sum of current year (250+2008-250 or 250+2007-250) and the original digit x100

And then, the definition of age = current year - birth year....so you are asked to subtract your year of birth from the resulting number above

And voila! you've reached your age + original digit x100

Of course, this will only work if your age is less than 100

Oh, and to make this work next year, use 1759 and 1758 instead of 1758 and 1757 respectively]
