Analysing Letter Coding Patterns
The question asks us to identify which pair among the given options does not follow the same logical pattern or coding rule as the others. We need to determine the relationship between the letters of the original word and the letters of its code.
Identifying the Common Pattern
Let's examine the alphabetical position shifts for each option provided in the question:
| Word: Code | Analysis of Alphabetical Position Shifts | Observed Pattern |
|---|---|---|
| ROSE: TQSC |
R (position 18) $\rightarrow$ T (20) = +2 O (15) $\rightarrow$ Q (17) = +2 S (19) $\rightarrow$ S (19) = 0 E (5) $\rightarrow$ C (3) = -2 |
+2, +2, 0, -2 |
| LION: NKOL |
L (12) $\rightarrow$ N (14) = +2 I (9) $\rightarrow$ K (11) = +2 O (15) $\rightarrow$ O (15) = 0 N (14) $\rightarrow$ L (12) = -2 |
+2, +2, 0, -2 |
| BEAR: DAWT |
B (2) $\rightarrow$ D (4) = +2 E (5) $\rightarrow$ A (1) = -4 A (1) $\rightarrow$ W (23) = -4 (wrapping around Z=26 to A=1) R (18) $\rightarrow$ T (20) = +2 |
+2, -4, -4, +2 |
| CAND: ECNB |
C (3) $\rightarrow$ E (5) = +2 A (1) $\rightarrow$ C (3) = +2 N (14) $\rightarrow$ N (14) = 0 D (4) $\rightarrow$ B (2) = -2 |
+2, +2, 0, -2 |
| TIGER: VKGCP |
T (20) $\rightarrow$ V (22) = +2 I (9) $\rightarrow$ K (11) = +2 G (7) $\rightarrow$ G (7) = 0 E (5) $\rightarrow$ C (3) = -2 R (18) $\rightarrow$ P (16) = -2 |
+2, +2, 0, -2, -2 |
We observe that the pairs ROSE: TQSC, LION: NKOL, and CAND: ECNB consistently follow the pattern of letter shifts: +2, +2, 0, -2.
The pair TIGER: VKGCP, being a five-letter word, follows a similar pattern extended by one step: +2, +2, 0, -2, -2.
Identifying the Outlier
The pair BEAR: DAWT (Option 3 in the question list) deviates from this established pattern, showing shifts of +2, -4, -4, +2.
The question specifies that the correct answer is BEAR: DAWI. Let's analyze this pair:
- B (2) $\rightarrow$ D (4) = +2
- E (5) $\rightarrow$ A (1) = -4
- A (1) $\rightarrow$ W (23) = -4 (using wrap-around)
- R (18) $\rightarrow$ I (9) = -9
The pattern for BEAR: DAWI is +2, -4, -4, -9. This sequence of shifts is significantly different from the +2, +2, 0, -2 (or its extension) pattern observed in ROSE, LION, CAND, and TIGER.
Therefore, BEAR: DAWI is the pair that does not belong to the group because it does not conform to the common letter-shifting logic.
Important Questions from Odd-One Out & Analogy
Three of the following four pairs have the same relationship between their elements as in the case of the pair BRIGHT: 24 and hence form a group. Which one does not belong to the group?
