## TCS Placement Paper Held on 5th Sept 2010 at Chaitanya Engineering College Visakhapatnam

Aptitude Test consists of 35 questions to answer in 1 hour with 0.33 Negative (–ve) marking for each wrong answer. (1 mark will be deducted for 3 wrong answers)

Cut off will be around 20 and one can score around 25 with min preparation.

Next rounds are Technical and HR.

Coming to questions first search for the numerical data in the questions and find the logic how the questions can be solved (as the Questions are very lengthy with 5 to 10 lines)

I don’t remember exactly all the Questions here are some which may help you all.

(NOTE: The Questions are repeating so its nic idea to just go through previous papers.)
