Q.papers (Durgapur )
Pattern = 5 * 8 =40
1…..A question will be given with six characters like AAABBB
16 MEANS YOU HAVE TO INTERCHANGE Ist character with VI th one and
then change the
charactert adjacent to it.
16 => AAABBB
BAABBA
BBABAA
25=> AAABBB
ABABAB
BBBAAA
34 => AAABBB
AABABB
ABBAAB
8 QUESTIONS MODEL
apply 25 &34 successively)
Apply 34 & 16 successively)
Apply 16 &16 successively)
Apply 25&25 successively) etc…….
Another question …
BAABBA CAME FROM APPLICATION OF
Choice 1. 34 & 25 successively.
Choice 2. 25 & 25 successively.
Choice 3. 34 & 34 successively.
Choice 4. 34 & 25 successively.
Answers and hints
If two conditions are being applied simultaneously the you will get same
answer.
e.g….suppose AAABBB…Apply 34& 34 then the result will be AAABBB
2. F(n,a,b,c) = AC if n=1
F(n,A,B,C) = F(n-1,A,C,B)+ F(1,A,B,C) + F(n-1,B,A,C)
This is the question.
find F(2,B,A,C) = F( 1,b,c,a)+ F(1,b,a,c)+F(1,a,b,c) =ba+bc+ac
Find F(2,C,A,B) = F( 1, c,b, a)+ F(1, c,a,b)+F(1,a,c,b) =ca+cb+ab
(one imp. Point ca not = bc); (ca+cb+ab) is not = (ab+cb+ca)
F(4,a,b,c) = ?= F(3,a,c,b) +F(1,a,b,c) +F(3,b,a,c)
F(3,a,c,b) = F(2,a,b,c) + F(1,a,c,b) +F(2,c,a,b)
F(2,a,b,c) = F(1,a,c,b) +F(1,a,b,c) +F(1,b,a,c)
So ab+Ac+bc = 3.
f(2,a,b,c) =3 ;f (3,a,b,c) = 3+1+3 = 7, f(4,a,bc,)= 7+1+7=15
Like this find f(5,a,b,c)= ?=( ans =31 pl. check)
Like this find f(3,a,b,c) =?
Q.3……
N= no of poles
R= No of flags
If N=5 and R=4
What are the possible ways the flag can be tag to the poll. 1st pole =
2,3,4
Ans=> 5*5*5*5 = 5to the power 4 = 625
Most probably choice (D)
If N=3 and R=3 and if the flag are identical what rae the diff. Ways
flags
can be tagged .
Ans+10 ( Please cross check)
If N=3 and R=3 and if flags and poles are identical
Ans => 3
If N=4 and R=3 and if both flag and poles are identical
Ans=> 3
If N= 5 and R=5 Two flags tied in the first pole one flag tied in the
third
pole what are the ways that the remaining flags can be tied.
Ans => 3*3*3
VERBAL( Answers are given in bracket)
Swan( not up)
Swan – song ( a musical piece)
Fools- cap (hat)
Fool- hardy (tough)
Band- wagon (Carriage)
Lady- bird( an avian creature)
Homour- bound(to0 tie)
Stare- case (cataegory)

Find the mirror image of the given figure when rotated 180 degrre
clockwise.
Find the mirror image of the given figure when rotated 180 degrre
anticlockwise.
Find the mirror image of the given figure when rotated 90 degrre
clockwise.

anticlockwise.
The given figure
90 degree anti….
