Ankita KatdareHere is the final questions list.
All the questions can be discussed here for solutions. 
gs131016thanks. please provide infosys,accenture and wipro latest pattern with solutions.

PraveenKumar PurushothamanIsn'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? 
CIVILPRINCESSthanks akd π
we've got TCS placement next monday π i don't have the aptitude test so my friends will be able to use them π 
Ankita Katdare@CP: The doc file only has questions. We need to discuss the solutions here. Can you give it a head start?
I have more questions to share.
PS: Some answers can be found elsewhere on the net, but the answers are different everywhere, so we need to find fullproof solutions here. 
CIVILPRINCESSi've solved some of those already. can we discuss them here itself? π

Ankita KatdareYeah, Please. Share the solutions here.
PS: It's highly likely that the same questions with different values will appear in the test. 
CIVILPRINCESSGiven 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
β’ 4
β’ 1
β’ 0
β’ 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... π

CIVILPRINCESSAfter 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?
β’ 11/12
β’ 1/12
β’ 0
β’ 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. 
Ankita Katdare@CP: A lot of people say the answer is 4, where 1 incentre and 3 exicenters are considered. (I have no idea about this π )

CIVILPRINCESSThere 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?
β’ 10 hours
β’ 8 hours
β’ 7 hours
β’ 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: TracenPoche Dynamic Geometry: Triangle: Incenter, Incircle, Excenter, Excircle, internal and external bisectors. College Geometry, SAT Prep. Elearningere 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.AbraKaDabra@CP: A lot of people say the answer is 4, where 1 incentre and 3 exicenters are considered. (I have no idea about this π ) 
Ankita KatdareGreat. Do answer the gold coin questions and dart question with solutions. There has been a lot of confusion over them too.

CIVILPRINCESSA 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?
β’ 0.5
β’ 0.25
β’ 0.75
β’ 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. 
lekhyaare u sure this is the new pattern for tcs????????????

Ankita Katdare@Lekhya: Yes, TCS just visited our campus and they followed this pattern. We don't think they will change it soon.

lekhyaok thank uππ

Krishna RadhikaAlok and Bhanu play the following minmax game. Given the expression N = 9 +
X + Y β Z where X, Y and Z are variables representing single digits (0 to 9), Alok
would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok
chooses a single digit number and Bhanu substitutes this for a variable of her choice
(X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the
value. Finally Alok proposes the value for the remaining variable. Assuming both play
to their optimal strategies, the value of N at the end of the game would be

Kaustubh Katdare
Start preparing with the aptitude questions (basic mathematics and logical reasoning along with Data Interpretation and Sufficiency type questions). Interview would be mostly about programming, your project and some totally irrelevant questions: #LinkSnipped# πuppala.roshniHi, I will be facing the TCS online test on Sept 7, 2011 and I donot know from where to start my preparation for.

CIVILPRINCESSone mistake in a problem that i solved.

the excentre is also to be considered since it will be equidistant from all the sides when they are extended. this i had not thought..CIVILPRINCESScheck out this link: TracenPoche Dynamic Geometry: Triangle: Incenter, Incircle, Excenter, Excircle, internal and external bisectors. College Geometry, SAT Prep. Elearningere 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.
but now there is a new thing that i found.
if it is an equilateral triangle then the no of excentre points would be three so the total points would be= 1(incentre)+3(excentre) =4.
but for an isosceles triangle the no of excentres to be considered are just two. therefore no of points = 1+2 =3
sorry for the confusion guys π

the answer for this would be= 20Krishna RadhikaAlok and Bhanu play the following minmax game. Given the expression N = 9 +

reason: when we have it like x+yz the maximum value would be 11 by cleverly placing the numbers. i'll post some examples for it in sometime. its just the same. just add the constant and 11. π

pls explain 
lakshmidharhey i have a doubt excentre is also equdistant from all the three lines know then we have the answer 4 is it corect or not

lakshmidharsince it is given as LINE it can be extendable so that we get 3 excentres and one incentres so answer is 4 otherwise if it is given as LINE SEGMENT ans is 1

lakshmidharif it is LINE it can be extendable so we get 3 excentres and 1 incentres so ans is 4. if it is LINE SEGMENT we cannot extend it so answer will be 1 incentre so ans is 1.

tinyFor the FIFA world cup, Paul the octopus has been predicting the winner of each
match with amazing success. It is rumored that in a match between 2 teams A
and B, Paul picks A with the same probability as A's chances of winning. Let's
assume such rumors to be true and that in a match between Ghana and Bolivia,
Ghana the stronger team has a probability of 2/3 of winning the game. What is
the probability that Paul will correctly pick the winner of the GhanaBolivia game?
β’ 5/9
β’ 1/9
β’ 2/3
β’ 4/9 somebody plz answer this one 
lekhyatake one team proability i.e ghana sa 2/3.
its complement is 1(2/3)=1/3
bolivia its winning proability is 1/3
and losing is 2/3
not the equation is p(winingof ghana and losing of bolivia)+p(wining of bolivia and losing of ghana)=(4/9)+(1/9)=(5/9)
this is the ans
all the best.
u can clear apti but concentrate in ur technical part during interview.

There are two boxes, one containing 10 red balls and the other containing 10
green balls. You are allowed to move the balls between the boxes so that when
you choose a box at random and a ball at random from the chosen box, the
probability of getting a red ball is maximized. This maximum probability is

ManishKumarVermais this the whole pattern or we have other section on aptitude and English also?
because 35 questions in 80 mins is quite easy i guess..
only logical reasoning????? 
CIVILPRINCESS
yup only one section. only logical puzzles...ManishKumarVermais this the whole pattern or we have other section on aptitude and English also?
because 35 questions in 80 mins is quite easy i guess..
only logical reasoning????? 
vincithanks for the questions i will join you within 7 days after having a look over these questions

lekhyacube prob:
volume=5*5*5=125
then reduce 2cm
so v=3*3*3=27
now 12527=98
find faces=98*6=588
gn 4 faces are painted so area=4*25=100
then 588100=488
balls prob:
take 2 boxes
transfer 9 red balls to another box so total balls in green box is(9+10)=19
now p(red ball in box1)=1
p(red ball in box2)=9/19
p(selectin box)=1/2
now eqn is
1*1/2 + (9/19)*(1/2)
verify the method frm ur frnds once........
gn no cycle of handshakes so n1=101=9
36 ppl
so the formula is n/3=36/3=12
check balls prob. once
