# 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.
-------------------------------------------------------------------------------------------------------------------------

2.2's complement of given Binary number

3. Octal Equivalent of a Binary number
