TCS Placement Paper Held on Sept 2011 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.)

1) There are two pipes A and B. If A filled 10 liters in hour B can fills 20 liters in same time. Likewise B can fill 10, 20, 40, 80,160….if B filled in (1/16) th of a tank in 3 hours, how much time will it take to fill completely?

– -> c) Chelsey is shorter than Juli

– -> d) Cannot determine who is taller among Chelsey and Juli

15) Dhoni and Ponting are waiting for the toss to happen. Umpire found that the coin to be tossed is missing. Ponting then takes a dice (1-6) from his pocket and asks the umpire to toss with it.

**Answer:**– (18+18+28)/4. Then you will get the 1 side of a square and now find the area of a square.i.e, side^24) One train travels 200m from A to B with 70 km/ph. and returns to A with 80kmph, what is the average of their speed?

**Answer:**apply 2xy/x+y5) An equation of the form 7x+17y+ 3z=54. Find the difference between x intercept and z intercept? Hint: x/a+y/b+z/c=1

**Answer:**convert the above equation to this form and see the difference between a and c then you will get the answer6) A man went 1mile to east den 1mile to north (un wanted stuff) and killed a bear what is the color of the bear?
