MACHINE INPUT

MACHINE INPUT

I have come across many candidates having problem with machine input question. so here i am providing a very simple trick for solving the same.....
but before going to trick lets understand what are different series that comes in question paper..
1. alphabetical series.
2. numerical series
3. mixed series
now gone are the days when in bank exam you will given alphabetical and numerical series. now mixed series are given mostly. therefore i will be explaining the mixed series as of now...

Mixed series is prepared in 3 ways...
1. alternate              =one 1 element is shifted/changed/ replaced or whatever you want to say that process.
2. alpha- number     = 2 elements are shifted at one time
3. alpha- no. -alpha =  3 elements at a time.

in this article i will be taking first case of mixed series..

first case ALTERNATE arrangement ( 1 element)

QUESTION=   G , 93 , Q  , 46 , 84  , N ,  F , 31
STEP 1.       =   31, G ,  93 ,  Q , 46  ,  84, N , F
STEP 2.       =   31 , Q,  G  ,  93 , 46 , 84 , N , F
STEP 3.       =   31 , Q , 46 ,  G ,  93 , 84 , N , F
STEP 4        =   31 , Q , 46 ,  N ,  G  , 93 , 84 , F
STEP 5        =   31 , Q , 46 ,  N ,  84 , G  , 93 , F

for solving any machine input first look at the last step. last step clearly shows alternate arrangement of the elements.

as the arrangement is alternate,it implies that only one element is shifted  at a time.
now come to the first and 2nd step to find which element was shifted.

once you know this much , you can solve any question based on this input.

the next fault i have seen in candidate is that they start writing the whole input step of the given question based on above given input...
this approach is very time consuming...

by studying the steps we can deduce following conclusions..
1. it is an alternate series.
2. first number is arranged and they are arranged in increasing order.
3. alphabets are arranged in decreasing order.

if you know this then there is no need to write any sequence....
simply mark the step number on the top of the given input just like this...

Now if question is what is the 1st step?
you can directly write the answer from your question ( look for red mark in pic. it has 1 written above 39)

as i have marked element 39 as 1 therefore it sud come on the first place so the answer is..
9,S.H,39,67,A,M,86,59

what is fourth step?
39,S,59,M,67,H,A,86 ( directly from the question... look at last line in the pic)

NOTE- 2 element shifting will be explained in the next article...
