telco 2002
two sections
aptitude
technical
technical is different for mechanical,matelargical and
same for
electrical and electronics
technical is very easy and contains only elementary
concepts
in aptitude there were 40 questions in 30 minutes
there were different sets with question no. changed
last 10 questions were on material science
like what is the role of sulphur in rubber
what is mixed in steel like that
curie temperature of .............
ans of one ques was doping
photodiode is made of si,ge,gallium aresnide none
newton's law of viscosity
luemn is unit of what
motor used in traction
remaining 30 questions are
*there are cars two red which are adjecent to each
other
four yellow
two green which are not adjecent
three blue which are adjecent
red and green are on the ends
now there were six questions
like if green is on 8th position then which is on 6th
or which cannot
be
there was one reading comprehension
and five questions
first question was on main theme
one of the question was if u have to devide this
passage in two parts
then what would be the first line of second passage
this passage was on (reading and writing skills)
so first part was on writing and next part was on
reading
remaining 19 questions were on mathematical apti
like an equation was given 2x3+kx2+7x+8
for what value of k (x+2)is a facotor of given
equation
answer of one question was 444(two trains are coming
towards each
other and one covers 60km more than the other tell the
total distance
covered )
some questions were engineering question type
like a car is running at some speed and break of some
retardation
was applied then what distance it will cover before
stopping
v2=u2+2as
basically the paper was easy and u can easy make it
in our(electrical) technical paper lots of electronics
questions were
there
then there was gd which is an elimination round
topics were
an organization needs leader not managers
if something is broken let it remains so
your dress is index of ur character
will globalization kill indian industry
disinvestment is good or bad
indian youths are more inclined towards monitoring
comforts rather
than challenging jobs
prepare and do well in gd and try to speak as much as
possibe and try
to put good points
they are looking for people who are good leader
try to lead the group
then interview is
core and little bit of hr
aptitude section
be fast as questions really need time
#2 questions from series completion----- answer of
one of which is 60
one completion of series of alphabets answer was
bab
#1 question was that if x* is greatest integer less
then that number then to find the value of the
sequence answer was 6
#1 question in which relation between x an y are
given in form of series of numbers, guess the relation
between x and y and complete the series
#1 question in which two linear equation was given, in
terms of variables x,m,z,y then to find the coorect
choice--- choices comprise of other relation between
the parameters
#1 question in which a ratio of a mixture composition
made of cement and some other materials was
given....to find the amount of cement
needed.......answer was 45
#2 or 3 simple question based on percentage and profit
and loss
#1 question based on BODMAS rule...... answer was
.0012
#1 question in which a square was inscribed in a
circle to find the area of square answer was
2a^2
#1 question in which it was given that xwill be greater than x but less
than y answer was
( x+y)/2
#1 question in which relation between g[x] and f[x]
was given then to find the relation between them is to
be found---------- confirm there is a correction in
this question so ask from them
#1 simple question based on time and distance
#2 question based on coding-decoding the trick of
first question was the two alphabets before the
alphabet of first word was the last alphabet of second
word the trick of second wasthe position of
alphabet in terms of no. (like A=1)from beginning and
from the end varies alternately
PASSAGE
a long passage was there based on principle of
induction that a shopkeeper offerd an apple to the
writer.....it was green and sour then he offers
another one which was also green and sour then when
the writer was offered the third one which was also
green he deducted that it is also sour so was then
discussed the nature of humanbeing to accept the
inference from induction.
then there was 5 to 6 question based on the passage
answer of 1 question was writer is from...... india
another one......... writer is a scientist
another one........apple has been used as ....... an
object of passage
question that what does "natural law" means........
answer is most probably...... induction
question that what does "extensive reference" means
question in which two statements was given and a
conclusion made on basis of them was given........it
represents syllogism
# quex. based on jigs and fixtures
# quex. based on carbon content in die steel
# return mechanism is not used in ....a . bore b.
planar ...
#what does 123+ .5 represents...
#angles r in the ratio 1:2:2... then the triangle
is.... isosceles
# distance between a &c is 60, a&b is 50 and b&c is
50.... find the shortest distance from pt. b on line
ac..... ans. 40 km.
ARRANGING QUESTIONS...
a question of arranging a series of mechanical
instruments on the side of a wall ...they were seven
in number........name of mechanical instruments was
given just to confuse you...... take the instruments
as lathe(l), polisher(p), air conditioner(a), H, B, D,
S
conditions... # lathe must always be at position 2
a&h must be together, s can stay with either b or
d.., lathe and polisher must not be adjacent...
# deduction... p can either be at 5 or 7(two questions
on this)
5 more questions on the above conditions
....... it is a simple question of arranging it.......
there were 5 to 6 question based on it
-----------------------------------------------------------------------
SOME MORE APTI QUESTIONS(SOME OF THEM MIGHT BE SAME)

100% has car or motorcycle then how many of them have
only car and motorcycle.
13.Two problems are based upon coding
