Title: Aptitude 5 Post by: Tanya on May 11, 2007, 01:10:02 PM 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.
