**Q52. Find the odd one out?**  
(a) JQK  
(b) BYC  
(c) LRM  
(d) CXD  
(e) OPX

Accepted Answer

**Solution:**

1. Convert each letter in the options to its alphabetical position:
   - A=1, B=2, ..., Z=26

2. Analyze the letter positions and the differences between consecutive letters:

- (a) JQK
  - J = 10, Q = 17, K = 11
  - Differences: +7 (10 to 17), -6 (17 to 11)

- (b) BYC
  - B = 2, Y = 25, C = 3
  - Differences: +23 (2 to 25), -22 (25 to 3)

- (c) LRM
  - L = 12, R = 18, M = 13
  - Differences: +6 (12 to 18), -5 (18 to 13)

- (d) CXD
  - C = 3, X = 24, D = 4
  - Differences: +21 (3 to 24), -20 (24 to 4)

- (e) OPX
  - O = 15, P = 16, X = 24
  - Differences: +1 (15 to 16), +8 (16 to 24)

3. Observe the pattern:
   - In options (a), (b), (c), and (d), the second letter is ahead of the first by a large positive number, but the third letter is behind the second letter by almost the same magnitude (negative difference).
   - In option (e), both differences are positive (+1 and +8), meaning the letters are in increasing order.

4. Therefore, option (e) OPX is the odd one out because its letter sequence does not follow the pattern of increasing then decreasing alphabetical positions.

**Answer:** (e) OPX
