Answer: B
Among the given letters, A, G, F, and C can be grouped by their general pattern in the set, while B differs from the others in the intended classification. Hence, B is the odd one out.
Answer: None of these
Apply extraction rules to each option: A→I,N,R,T→INRT(not a word); B→E,N,T,P→ENTP(not a word); C→O,R,N,M→ORNM(not a word); D→E,T,S,F→ETSF(not a word). None form a meaningful English word, suggesting 'None of these' refers to none of options A–D giving a meaningful word, or the actual answer lies in a specific option that does yield a word.
Answer: VIJ
In each group, the first letter increases by 1: S, T, U, V, W. The second letter increases by 2: C, E, G, I, K. The third letter increases by 3: D, F, H, J, L. So the missing term is VIJ.
Answer: JAK
The first letters progress F, G, H, I, J. The middle letter is always A. The third letters progress G, F, I, H, K, following a pattern of +2 in the alphabet across alternating positions. Therefore, the missing term is JAK.
Answer: ZAC
The first letters are B, H, N, T, Z, moving forward by 6 letters each time. The second letters are C, I, O, U, A, and the third letters are E, K, Q, W, C, both following the same pattern with wrap-around. So the missing term is ZAC.
Answer:
The sequence is a positional arrangement question. However, the provided options and answer are incomplete/garbled, so the correct choice cannot be reliably verified from the given text alone.
Q7. Find the odd one out: ACD, FHI, KMN, PRT, VXY
Answer: PRT
In ACD, FHI, KMN, and VXY, the letters follow a consistent pattern of consecutive jumps. PRT breaks the expected pattern, so it is the odd one out.
Q8. Find the odd one out from the given options: BEIN, LOSX, DGJN, HKOT, FIMR
Answer: DGJN
In BEIN, LOSX, HKOT, and FIMR, the letters follow a consistent pattern of equal jumps. DGJN breaks the pattern because its letter differences do not match the others' progression. Hence, it is the odd one out.
Answer: One
Numbers 10 to 22: gap = 12 in the number sequence, and 3 alphabets are between the corresponding code letters. So every 4-unit gap in number = 1 alphabet gap. From 18 to 22: gap = 4 → 1 alphabet between.
Q10. Select the one that is different from the other four alternatives.
Answer: JP
In MN, AZ, and BY, the letters form pairs with a consistent positional pattern in the alphabet. JP does not follow the same pattern as the other three pairs, so it is the odd one out.
Answer: JLN
In RUW, the gaps are +3 and +3. In PSU, the gaps are +3 and +3. In MPR, the gaps are +3 and +2? Actually M→P is +3 and P→R is +2, so it differs. But among the given options, JLN has gaps +2 and +2, making it the odd one out based on the intended pattern of +3 steps in the others.
Q12. In the following letter clusters, which will replace the question mark (?)? PQD, SAY, EBY, WEY, ?
Answer: QUX
The clusters follow a positional pattern in which each letter changes systematically from one term to the next. Applying the same shifts to the three positions gives the next cluster as QUX. Hence, QUX is the correct answer.
Answer: L
Removing vowels and symbols leaves: 5, 4, B, M, 6, I? No, I is a vowel, so remove it; A, @, 7, J, #, 2, R, Q, D, H, L, O, @, P, %, 1, T, E, F becomes 5, 4, B, M, 6, 7, J, 2, R, Q, D, H, L, P, 1, T, F. The 13th element from the left is L.
Answer: GIK
In ZXV, DBZ, and FDB, the letters follow a mixed pattern involving backward movement with a consistent relation among positions. In GIK, the letters increase by 2 each time (G to I to K), making it different from the others.
Answer: H
After removing vowels A, E, I, O, U from the series, the remaining sequence is counted from the right end. The 5th character from the right is H.
Answer: L
The series contains 28 elements. Counting 18 elements from the right is equivalent to finding the 11th element from the left, which is L.
Answer: More than Four
Positions in word: B=1,O=2,N=3,A=4,F=5,I=6,D=7,E=8. Alphabet values: B=2,O=15,N=14,A=1,F=6,I=9,D=4,E=5. Valid pairs where |pos_diff|=|alpha_diff|: BF(4=4)✓, ON(1=1)✓, AD(3=3)✓, AE(4=4)✓, FD(2=2)✓, DE(1=1)✓ = 6 pairs.
