A.1
B.3
C.2
D.4
Solution
Address matching
Compare each with the given address: 2 changes the sector (13), 3 misspells "Oas", 4 changes the PIN (201302).
Only address 1 is an exact match.
Hence option (a).
12
Find the option that best completes the analogy.
DP : LX :: BH : ?
A.LO
B.JP
C.1O
D.IW
Solution
Letter-pair analogy (+8)
D+8 = L and P+8 = X — both letters advance by 8.
Apply the same: B+8 = J and H+8 = P.
Hence JP — option (b).
13
Ram is facing North. Sita is seated second to the right of Ram. Who is sitting immediately to the left of Sita?
A.The person seated to the immediate right of Ram
B.The person seated opposite to Ram
C.The person seated to the immediate left of Ram
D.Cannot be determined
Solution
Direction/position logic
With everyone facing North, positions to the right of Ram run: 1st right, then 2nd right (Sita).
The seat immediately to the left of Sita is therefore the seat between Ram and Sita.
That is exactly the person seated to the immediate right of Ram — option (a).
14
In the following question, the second word is related to the first word by a specific pattern of letter transformation. Identify the same pattern and apply it to the third word to find the correct option that completes the analogy.
HOME : JPOG :: TONE : ?
A.VJTF
B.VPPG
C.VPSF
D.ZPOG
Solution
Word coding (+2, +1, +2, +2)
HOME → JPOG: H+2 = J, O+1 = P, M+2 = O, E+2 = G.
Apply the same +2, +1, +2, +2 to TONE: T+2 = V, O+1 = P, N+2 = P, E+2 = G.
Hence VPPG — option (b).
15
In each of the following questions, a specific pattern such as reversal or rearrangement has been applied to the first word to get the second. Apply the same pattern to the third word and find the correct answer from the given options.
REVERSE : ESREVER :: STAMINA : ?
A.ANIMAST
B.ANIMATS
C.NAIMAST
D.NAIAMST
Solution
Word reversal
ESREVER is simply REVERSE written backwards.
Writing STAMINA backwards letter-by-letter gives A, N, I, M, A, T, S.
Hence ANIMATS — option (b).
16
In each of the following questions, the first word is coded to form the second word using a specific rearrangement and/or substitution rule. Apply the same rule to the third word to determine the correct corresponding word from the given alternatives.
MDREDBS : OFTGFDU :: BZSSKD : ?
A.DUUJMF
B.DFBUUC
C.DBUUMF
D.DBUUFM
Solution
Word coding (reverse + 2)
MDREDBS → OFTGFDU: every letter moves 2 places ahead (M+2 = O, D+2 = F, R+2 = T …).
Apply +2 to BZSSKD: B→D, Z→B (cyclic), S→U, S→U, K→M, D→F.
Hence DBUUMF — option (c).
17
Identify the odd one:
3, 5, 7, 11, 14, 17, 19, 23
A.11
B.14
C.19
D.23
Solution
Odd one out — primes
All the numbers in the list are prime numbers except one.
14 = 2 × 7, so it is composite.
Hence 14 is the odd one — option (b).
18
Which of the following is the odd one out?
A.5, 7, 11
B.13, 17, 19
C.9, 12, 15
D.23, 29, 31
Solution
Odd group — primes
Options (a), (b) and (d) are groups of prime numbers.
9, 12 and 15 are all composite (divisible by 3).
Hence option (c) is the odd group.
19
Kabita said, "The man sitting on the bike is my mother's son-in-law." Who is the man to Kabita?
A.Husband
B.Brother
C.Son
D.Cousin
Solution
Blood relation
Kabita's mother's son-in-law is the husband of the mother's daughter.
Taking Kabita as that daughter, the man is her own husband.
Hence Husband — option (a).
20
In each of the following questions, a group of three numbers/symbols is given in each option. Identify the group that does NOT follow the same pattern as the others.
A.P22 : N20 : L18
B.R24 : P22 : N20
C.T26 : R24 : P22
D.S25 : P22 : M18
Solution
Odd group — letter/number gap
In (a), (b), (c): the number = letter-position + 6, and each step moves the letter back by 2 and the number down by 2.
In (d): S25 and P22 keep the +6 rule, but the step S→P is −3 while P→M with 22→18 mixes −3 letters with −4 numbers.
The uniform −2/−2 pattern breaks — hence option (d).
21
In each of the following questions, a group of three numbers/symbols is given in each option. Identify the group that does NOT follow the same pattern as the others.
A.M7@ : N8# : O9$
B.P10@ : Q11# : R12$
C.S13@ : T14# : U15$
D.V16# : W17$ : X18%
Solution
Odd group — symbol cycle
In (a), (b), (c): letters and numbers advance by 1, and the symbols always follow the cycle @, #, $.
In (d) the letters/numbers advance correctly, but the symbols run #, $, % instead of starting from @.
Hence option (d) breaks the pattern.
22

The same 25 questions, but with a timer and the answers hidden — 15 minutes.
Each letter of a term moves 4 places ahead in the next term (cyclically after Z).
S+4 = W, W+4 = A, A+4 = E.
So the next cluster is WAE — option (b).
1st letters: N, O, P, Q → R (+1 each time).
2nd letters: J, K, L, M → N (+1); 3rd letters: M, L, K, J → I (−1).
So the next cluster is RNI — option (d).
1st letters: E, H, K, N → Q (+3, cyclic).
2nd letters: U, X, A, D → G (+3); 3rd letters: H, J, L, N → P (+2).
So the next cluster is QGP — option (b).
The 1st letter W stays fixed throughout.
2nd letters: V, R, N, J → F (−4); 3rd letters: O, G, Y, Q → I (−8, cyclic); 4th letters: H, V, J, X → L (+14, cyclic).
So the next cluster is WFIL — option (c).
1st letters: N, O, P, Q → R (+1); 2nd letters: E, G, I, K → M (+2).
3rd letters: K, P, U, Z → E (+5, cyclic); 4th letters: P, W, D, K → R (+7, cyclic).
So the next cluster is RMER — option (a).
The pattern alternates: +9, then −5, repeatedly.
7+9 = 16, 16−5 = 11, 11+9 = 20, 20−5 = 15, 15+9 = 24, 24−5 = 19.
Next: 19+9 = 28 — option (d).
STATICS arranged alphabetically: A, C, I, S, S, T, T.
Second letter from the right = T; fourth letter from the left = S.
Between S and T in the alphabet there is no letter — 0; option (a).
D+8 = L and P+8 = X — both letters advance by 8.
Apply the same: B+8 = J and H+8 = P.
Hence JP — option (b).
With everyone facing North, positions to the right of Ram run: 1st right, then 2nd right (Sita).
The seat immediately to the left of Sita is therefore the seat between Ram and Sita.
That is exactly the person seated to the immediate right of Ram — option (a).
HOME → JPOG: H+2 = J, O+1 = P, M+2 = O, E+2 = G.
Apply the same +2, +1, +2, +2 to TONE: T+2 = V, O+1 = P, N+2 = P, E+2 = G.
Hence VPPG — option (b).
ESREVER is simply REVERSE written backwards.
Writing STAMINA backwards letter-by-letter gives A, N, I, M, A, T, S.
Hence ANIMATS — option (b).
MDREDBS → OFTGFDU: every letter moves 2 places ahead (M+2 = O, D+2 = F, R+2 = T …).
Apply +2 to BZSSKD: B→D, Z→B (cyclic), S→U, S→U, K→M, D→F.
Hence DBUUMF — option (c).
Kabita's mother's son-in-law is the husband of the mother's daughter.
Taking Kabita as that daughter, the man is her own husband.
Hence Husband — option (a).
In (a), (b), (c): the number = letter-position + 6, and each step moves the letter back by 2 and the number down by 2.
In (d): S25 and P22 keep the +6 rule, but the step S→P is −3 while P→M with 22→18 mixes −3 letters with −4 numbers.
The uniform −2/−2 pattern breaks — hence option (d).
In (a), (b), (c): letters and numbers advance by 1, and the symbols always follow the cycle @, #, $.
In (d) the letters/numbers advance correctly, but the symbols run #, $, % instead of starting from @.
Hence option (d) breaks the pattern.
The only daughter of Sushma's father is Sushma herself.
So the man's mother is Sushma.
Hence the man is her Son — option (a).
Tom's uncle's only son is Tom's cousin.
Alka is that cousin's wife.
A cousin's wife is one's sister-in-law — option (c).
Nakul's mother's husband is his father; the father's only son is Nakul himself.
"Your sister's brother" is simply you.
So Nakul is the father of you — option (b).
