    square root of(123454321)=? the answer will be 11111

    Tell you how to find at first look.

    First check the number is consecutive from 1.
    Then check whether goes like 1 2 3 then 2 1 (ie 1 2 3 4 5 6 7 6 5 4 3 2 1)
    Now find the number which is the biggest. That is the number of 1s in the answer.

    For ex

    sq rt(12321)=111
    sq rt(12345654321)=111111

    I would tell you easy method of finding shortcuts of square roots.

    Suppose, if they are asking find square root for 729

    The quickest answer that should come around is it must be from 25 to 30.

    In my last shortcut method, I said finding or multiplying 5 squares, so it would be easy for you to find any 5 squares.

    STEP 1: Given the square root is 729, always check the last digit, ie. 9 ( Squares of 3 and 7 we would get 9)
    STEP 2: so the answer should be 27.

    Another way of finding square roots is

    25 * 25 = 625 30 * 30 = 900, so the given squaree root is 729, and the answer should be 27.

    If you have any doubts on squaring or mulitiplying by 5 ask me, I wud explain abt it

    Okay, I will explain about Syllogism

    But it requires time to draw the diagram in here...

    Syllogism is quite easy..

    I have opened a new thread on mathematical shortcuts and syllogism.

    So, I would be posting my tutorials there, Ppl who are preparing for competitive exams could take a look @ it.

    Hi Shinara,

    How is preparation for SBIPO going? I'm also preparing for it. I'm going to start solving previous question papers on PO/MT from today onwards.

    Hi rakinya,

    The specialist officcer exam was a flop... I din't practice well so i couldn't manage time. I know i have to work hard for SBIPO but my project work also going on... Hope i can atleast glance something at last moment... Good you started preparing... Really some question were so simple like 234.4+343.3+123.2=? but i spent much time in tough questions so i couldn't even do those simple questions :-(
