I2 PAPER (IIT kanpur) 14/8/98

IN THIS THERE ARE TWO PAPERS EACH OF ONE HOUR.ONE IS ANALYTICAL
AND THE OTHER IS TECHNIQAL PAPER.

ANALYTICAL PAPER: IN THIS THERE ARE 3 PARTS

PART A: THERE ARE ABOUT 45 QUESTIONS.IN EACH THERE ARE
TWO SENTENCES.YOU HAVE TO SELECT THE TRUE STATEMENT.

FOR EXAMPLE--1
1.LUCK PLAYS GREAT ROLE TO GET SUCCESS
2.IF WE WORK HARD WE GET SUCCESS.

while answering these questions you should be careful because
many questions will be repeated ie., one question will be
all that questions.

PART B: IN THIS THERE ARE ABOUT 4 SECTIONS. IN EACH SECTION
THERE ARE 15 BITS.
SECTION 1---
SECTION 2--- INFERENCES,
SECTION 3--- CONCLUSIONS
SECTION 4--- ASSUMPTIONS

PART C: THERE IS NEGATIVE MARKING IN THIS PART.THIS IS
COMPREHENSIVE.THERE ARE 10 QUESTIONS.

************************************************************************
(I am unable to reproduce questions as itis. iam writing them
in my own words questions are same just language different)

TECHNICAL PAPER :: IN THIS THERE ARE TWO PARTS

PART 1: THERE ARE 20 MULTIPLE CHOICE QUESTIONS .EACH QUESTION
CARRIES 3 MARKS.THERE IS NEGATIVE MARKING FOR EACH WRONG ANSWER
MINUS 1 MARK.HERE ARE SOME QUESTIONS OF THIS PART.

exact question)

PART 2:
HERE A PROBLEM IS DEFINED YOU HAVE TO WRITE A
PROGRAMME IN C OR C++

TWO SCHOOLS,HAVING DIFFERENT NO. OF CLASSES . EACH CLASS HAS
DIFFERENT NO. OF SECTIONS.THE 2 SCHOOLS HAVE TO BE MERGED
TOGETHR SO THAT A STUDENT OF SAME CLASS AND SECTION REMAIN
SAME. FOR EXAMPLE, 1A STUDENTS OF BOTH SCHOOLS SHOULD BE IN 1A
SECTION OF NEW SCHOOL

WRITE A PROGRAM FOR THE ABOVE USING
1) DYNAMIC MEMORY ALLOCATION
2) SRUCTURES
3)

************************************************************************

in iitk about 400 students attended for written test and
only 18 students were shortlisted . after interview they
have selected only 8 students ( 1 from mtech and 7 from btech)

BEST OF LUCK

one to one negative marking is there.it is tough to qualify
unless u know the paper.totally there are 105 questions. 70 min. three
flow sheets---- 10 min. sections are quantitative(23),analytical(about
20) ,series&venn diagrams,logical(20) questions from a passage (about
10). time span for each section is different.sit at the back so that u
can turn pages if u want.different colored papers
are used. for flow sheets first one is relatively easy
1.u will be given conditions like
if a wins he gets 100 pts,if b wins he gets 50 pts etc
2.there is flow sheet& there are empty cells(4) at "yes' or 'no"
decision
points.
3.for each cell 4 choices will be given which should be chosen by
following through initial conditions &flow sheet logic.
4.rem. -ve marking is there. no verbal questions.

rs aggarwals verbal& nonverbal book verbal--- pg. 254 pr. 53
to56(almost same) 246 eg.2 pg 104 exer.3a about 5to 6 series
qu.are there.so do well
pg.354-355 8,13,
6th doubt 4 conclusions r there in all ques.
pg.115----qu.36 nonverbal----pg.5 41,54,108,145,158 241 is doubtful
--------------- ans. to one quant. is 200/3 %

anals
1.six persons will be there.
killer,victim,hangman,judge,police,vitness
a,b, c,d,e,f u have to match conditions like,a is the last person to
the
victim alive,will be given as clues.so we can conclude that a is the
killer. this is an easy one .paragraph will be very big .don' worry 5
to 6
ques. 2. 5 persons will be there. cashier,
A
clerk,buyer,manager,floorwalker(check in info. paper for exact ques.)
a,b,c,d,e will be their names. conditions will be given&we have to
match
who is who 3 r women&2 r men in this sample condition, cashier&clerk if
get married, b will be wise man mrs.c husband has some business prob
with
manager manager&cashier(or clerk) r classmates etc. will be given

do quantitative qu. from back.

data graphs on turnover,gross profit &net profit will be given& u have
extract data from that &find out few ratios.(easy one)

it is moving with v2 km/hr then what is the speed of the stream.
ans: 13 check the values of v1 and v2 are given
to find ans (v+s = v1, v-s = v2 find the boat velocity)

(2) 0.75 * 0.75 * 0.75 - 0.001
--------------------------------
0.75*0.75-0.075+0.01

(3) A can work done in 8 days
B can work three timesfaster than the A;
C can work five times faster asthe A;
ans : 8/9 it is correct place blindly.

(4) one answer is 200/3 % it is perfectly correct i cannot recollect
the prob. so place it blindly.

(5) A car is journied a certain distance in 7 hrs in forward journey
in the return journey increased speed 12km/hr takes the times 5 hrs.
what is the distance ans:210 it is perfect place blindly.

the percentage of error
ans we dont know but he has gived 14 18 25 andsome answers less than

(7) x + 4 y
--------- relation between x and y is x/2y = 3/2 ie x = 3y find the

only these questions see rs agarwal reasoning verbal and nonverbal book
new edition asthe page numbers i already sended to you.
ansers he changed slitely see.

From two fig 6 questions regarding the swimmers,girls,tennisplayers,tall and
second one on politicians,graduates,parliament members, both questions
are same given so mugup and go to exam and place blindly i already
sended the page numbers in previous mail.

series:(1) R,M,(..),F,D,(..)
ans: I,C
(2) (...),ayw,gec,mki,sqo ans: usq.
(3) 1,3,4,8,15,27, ans: 50
(4) 0,2,3,5,8,10,15,17,24,26,.. ans: 35
(5) 2,5,9,19,37,.. ans:75

these are the correct ansers place it blindly.

the figure series which i had already send in the earlier paper is
same and one extra qestion is their it is this type
box type in side the box line and dot.
this type see in the new edition rs agerwal a box is their
in the answer so try for question in rs agerwal

see rs agerwal for statements and assemptions questions.

As per my experience I attempted only 32 questions out of 105
and i was topper among the 35 who shortlisted for interview.
In IITD also the same thing was happened.
cut off will be around 30 out of 105.
the above 35 questions aare enough to qualify.
remaining questions if u know exact answers then place .
otherwise simply leave it.
