they already
have.
Then C gave A and B the same number of marbles
they already
have.
At the end A,B,and C have equal number of marbles.

(d) 39

Ans. (d)


3. If a car starts from A towards B with some
velocity.
Due to some problem in the engine after travelling
30km, the
car goes with 4/5 th of its actual velocity
The car reaches B 45 min later to the actual time.
If the car engine fails ofter travelling 45km, the
car
reaches the destination B 36min late to the actual
time
What is the initial velocity of car and what is
the distance
between A and B in km

Ans. 20 & 130.


4. A person has Rs 100/- in his pocket, he can as 25
pencils or 15
books.
He kept 15% of the money for travelling expenses

eg: chief : tribe :: governer : state
epaulette : shoulder :: tiara : head

hammer : carpenter ::


6. The values of shares (in Rs).of A, B and C from
January to June
are as follows.

Month A B C
January 30 60 80
February 35 65 85
March 45 75 65
April 40 75 82
May 55 75 85
June 50 75 80

i) During this period which share has undergone
maximium
fluctuation?
ii) In which month it is possible to buy B and C
selling A?
iii) In which month the share values are very low?
iv) By purchasing one share of A and 4 each of B and C
in the
beginning of the period,
when shoudl these be sold to get maximum profit?


7. In a computer institute 9 languages can be taught.
The module is of 6 months duration and of the six
languages
only one can be taught each month .
In addition to that BASIC is always taught and
should be in
first month itself

WORD PERFECT is to be taught in the preceeding week of
WORD
STAR.
FORTRAN can not be taught until COBAL is taught prior
to that
BINO, FIFO can never be taught in single module
languages are BASIC, WORD STAR, WORD PERFECT, FORTRAN,
COBAL,
BINO, FIFO, LOTUS, C

i) If word star is in 3rd month , what could be in 6th
month.
ii) If COBAL is in the 2nd month and BINO in 6th
month. FORTRAN
will be taught in which month.


I am sorry if any answer goes wrong but i don't think so
