For those born in the 20th century.

Think of a number from 1 to 7.

With the help of this secret number, you will do five operations. You will get something very revealing about yourself.

Follow these steps:

1. Multiply this number by 2
2. Add 2
3. Multiply the result by 50
4. If your birthday has already passed this year, add 25, otherwise add 24
5. Subtract the last two digits of the year of your birth.

The result is a three digit number. The first one is the number that you thought and the last two are… your age!

Note: This astuteness is valid for the year 2025. For 2026, you must add one unit to the numbers referred in point 4. For 2027, two units and so on.
