TCS Placement-Paper

Hi Friends,

Here are some questions asked in TCS placement drive held in Vel tech, Chennai.

Only 2 rounds. First aptitude round. Online test.


Here there are 35 questions only maths. No verbal and nonverbal.

All 35 questions are from quantitative aptitude.

Time is one hour.

Most of the questions will be in paragraph type.

Irrevelant informations will be there.

But we have to choose only the datas which are relate to the question. I heard that these questions are prepared by IIT atudents but it is not worth. Just one week preparation is more than enough.


More than that time management is more important. Prepare yourself on the following topics:ages,percentages,ratio and proportion,numbers,time and distance,directions,sequence,time and work,probability,blood relation.



Try to attend 20 questions which should be absolutely correct.

There is negative marking for the wrong answers.
