I just love these mathematicians to come up with these tricks like this one.
1. Count how many consonant letters are in your MOM’s first name (Not last name).
2. Multiply the number with 2.
3. Add the result with 5.
4. Multiply the sum with 50.
5. Add the result with 1763.
6. Subtract the sum with your year of birth (full 4 digits).
7. The last 2 digits of the result is YOUR AGE.
