Placement Papers - L & T Infotech

There are 2 parts
 1. Technical  
 2. Aptitude ( whole based on related figures not mathematical questions )

Aptitude:
 
  IDENTIFY THE UNKNOWN FIGURE FROM GIVEN RELATED FIGURES>
 
   3 -  sets of figures(SHAPES ) ARE GIVEN .EACH SET HAVING THREE FIGURES
   LAST SHAPE OF THIRD SET Will be missing and you HAVE TO IDENTIFY it BY CHECKING OTHER COMBINATIONS 

          A1 A2 A3         
          B1 B2 B3
          C1 C2 X   Find X?
         
        Given 8 number of choices.
         
(some times X is decided by whole combinations ie, A1, A2 ,A3,B1,B2,B3,C1,C2)

  Some combinations will be complicated .So be calm and quite when attendung the aptitude test.Care must be taken to utilize the allocated time perfectly since you have only 30 minutes for 36 questions and you have to deal with some complex figures (I think in the middle part given combinations were complex ;complex means very complex).
 My advise is to be practise well before attending the test.Since Tchnical part is not hard your fate is decided by aptitude
 Test only.

Technical:

  There are 40 Questions and 4 choises for each
  Duration : 30 minutes

-----NOTE :--------------------------------------------------------------------------------------------------------------
I list here some Questions and some choices that i do remember, as it is. Some times there may be mistakes in Questions and choices.My intension is to present how the test would be.
-------------------------------------------------------------------------------------------------------------------------

  1. a( [ B ( [A^ C]]
   where \'(\' and \'^\' are symbols related to SET and \'^\' is not exact symbol , it is curved not conical(due to limitation of key board ), represents"union"
  a. has no sense 
  b.It is associative as well as commutative

 2.2\'s complement of given Binary number

 3. Octal Equivalent of a Binary number
 
 4.Given -- 
     Ac + AB + BC =
   a. AC   
   b. BC+AC

5. Question related to linked list

  Given a program coding in C++ and asked what it is doing.class definition not given
    choices were a. Deleting a node
         b. Adding a node at head
         c. Adding a nde at end
           
  I think it is adding a node at the head of the node.
 

  Note:
 
  You must go through linked list verywell both class definition and program to adding the node ,deleting the node, initialising the linked list etc..
 
6.Some Questions related to data structures like
  traversing through
   QUEUE
   TREE  etc.

7.Evaluate given polish prefix expression ( I am not remembering the expression)

8. LIST| Sort | MORE 
   a. Lists the files after sorting and diplay "more"
   b. List or sort the file and ask for any more files
  ( I do remember only these two choises )
    

9. Copy QUEUE/SORT TXT.axb QUEUE/AJITH
   cd QUEUE/AJITH
   ren TXT*.AXB TXT*.ayb
   DEL *.ayb
   DIR

  What are the files listed?
  choices    
  a. only \'.\' and \'..\'
  b. all files starting TXT
  c. No files listed 
  
10. 1 simple question from COBOL
