TCS Latest Campus Placement Papers 2011 (New Pattern) With Solutions

thanks. please provide infosys,accenture and wipro latest pattern with solutions.

Isn't it solved? Where are the solutions? Can we discuss the answers in some thread?

@AKD: Once this is solved, I am planning to host it in my Quiz Engine. What say?

thanks akd

we've got TCS placement next monday i don't have the aptitude test so my friends will be able to use them

i've solved some of those already. can we discuss them here itself?

Given 3 lines in the plane such that the points of intersection form a triangle with
sides of length 20, 20 and 30, the number of points equidistant from all the 3
lines is
• 4
• 1
• 0
• 3

solution:
answer is 1. and that point is called incentre.

explanation:
now take a triangle and inscribe a circle inside the triangle. the circle must touch all the sides of the triangle as shown in the figure.



the radius of the circle will equidistant from all sides since the circle touches all three sides. there exists only one such point...

After the typist writes 12 letters and addresses 12 envelopes, she inserts the
letters randomly into the envelopes (1 letter per envelope). What is the probability
that exactly 1 letter is inserted in an improper envelope?
• 11/12
• 1/12
• 0
• 12/212

answer: 0

explanation:

if one letter is inside a wrong envelope then there should be another one too which is in the wrong envelope. so the event of one error is impossible. so probability is 0.

There are two water tanks A and B, A is much smaller than B. While water fills at
the rate of one litre every hour in A, it gets filled up like 10, 20, 40, 80, 160 .. in
tank B. (At the end of first hour, B has 10 litres, second hour it has 20, and so
on). If 1/32 of B's volume is filled after 3 hours, what is the total duration required
to fill it completely?
• 10 hours
• 8 hours
• 7 hours
• 9 hours

answer:

explanation:

1/32 filled in 3 hours.
in the next hour it will double the content in it...
i.e. 1/16 in in 4 hours
1/8 in in 5 hours
1/4 in in 6 hours
1/2 in in 7 hours
full in 8 hours

check out this link: http://gogeometry.com/geometry/incenter_excenter_incircle_excircle.htm

here three epicentres and incentre are drawn. the question asks for the point which is at the same time equidistant from all sides. the epicentres are not equidistant from all sides.

A circular dartboard of radius 1 foot is at a distance of 20 feet from you. You
throw a dart at it and it hits the dartboard at some point Q in the circle. What is
the probability that Q is closer to the center of the circle than the periphery?
• 0.5
• 0.25
• 0.75
• 1

answer: .25

explanation:
the probability is= (area we need to consider)/ (total area of the dartboard) = (pi (r/2)^2)/(pi r^2) =.25



P.S: these solutions may be wrong. so CEans please correct them if mistake found.

are u sure this is the new pattern for tcs????????????

ok thank u

Which colg are u in????????????????????????

Thank you very much upload the TCS paper.plz will you upload the answers of these papers
