Aptitude 5
Pattern = 5 * 8 =40
1…..A question will be givem 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 QUESTIONSA MODEL
(I. apply 25 &34 successively)
(II. Apply 34 & 16 successively)
(III. Apply 16 &16 successively)
(IV. Apply 25&25 successively) etc…….
Another question …
I. BAABBA CAME FROM APPLICATION OF
Choice 1. 34 & 25 succesively.
Choice 2. 25 & 25 succesively.
Choice 3. 34 & 34 succesively.
Choice 4. 34 & 25 succesively.
Answers and hints
1. 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.
i. find F(2,B,A,C) = F( 1,b,c,a)+ F(1,b,a,c)+F(1,a,b,c) =ba+bc+ac
ii. 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)
iii. 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
1. Swan( not up)
2. Swan – song ( a musical piece)
3. Fools- cap(hat)
4. Fool- hardy (tough)
5. Band- wagon(Carriage)
6. Lady- bird( an avian creature)
7. Homour- bound(to0 tie)
8. Stare- case(cataegory)
