    The Ans is : ((9-7)*9)-7

    I think you people got misunderstood with the question.

    You have to use all the digits, in any order with the help of operator provided (any).

    - appear twice and +,/ does not appear at all.

    But, nice try Sameer :)

    Ohh My God :O

    @ All, I am very much sorry, my apology that I couldn't reply earlier and all this thing happend.

    Actualy I had my exams and weekely off so couldn't reply :(

    Yes, Sameer is right, this was very tricky question and I also couldn't expect anyone to answer as some of my frds who are CAT champs even couldn't solve this.

    The questions is so simple but because of it's way of asking, anyone can get confused.

    Sameer got it right.

    The rest is with Shabbir :D

    Sorry Once again :(

    He may be right when it comes to answer but that answer does not satisfy all your conditions you mentioned

    He satisfied this

    All the operations are not used.

    Have you missed something ?

    Nop Shabbir, as I said, it was a tricky question.

    As he said

    At least one solution contains the following operations, used exactly once each, but not necessarily in the order given:

    It has two parts.

    1. At least one solution contains the following operations
    2. Used exactly once each, but not necessarily in the order given

    I am agree that this was very tricky question...as you will have to understand as you have to use all the digits, in any order with the help of operator provided.

    Me and someof my frds who are CAT Champs also got confused and got surprised when we found the solution :D
