    Here is one you can try on your friends!

    -->Think of a number between 1 and 10.
    Example: 6

    -->Double it.
    Example: 12

    --> Now add 10 to the answer.
    Example: 22

    --> Divide by 2.
    Example: 11

    -->Now tell me what number do you have now.
    Example: 11

    --> (The friend replied : Your number was 6)
    How ? The number I told him (11), was 5 more than the initial number I guesses. So he substracted 5 from the number (11) I told him.

    If you follow the same rule, reduce 5 from the number your friends tell you. and Gotta! You can tell which number they were thinking......
