Mind trick - The Number 5

THE NUMBER 5 TRICK

Ask somebody to think of a number and keep it secret.

Then ask that person to double the secret number and then multiply by 5. 

Ask for the total.

Whatever the total is, knock off the last digit 

and you will have the secret number the person mentally chose at the start.

For example:

Secret Number: 8

Double the secret number: 8+8=16

Multiply by 5: 16x5

Ask for the total: 80

Knock off the last digit: 0

The answer is: 8
