L&T INFOTECH PAPER 1 January 2005
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

5. Question related to linked list
Given a program coding in C++ and asked what it is doing.class definition not
given

adding the node ,deleting the node, initialising the linked list etc..
