Four letter clusters have been given, out of which three are alike in some manner and one is different. Select the letter cluster that is different.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. XZTB.
The logic used here is:
1st letter + 2 = 2nd letter
2nd letter - 5 = 3rd letter
3rd letter + 7 = 4th letter
Option 1: BDYF
B + 2 = D
D - 5 = Y
Y + 7 = F
This follows the logic.
Option 2: XZTB
X + 2 = Z
Z - 5 = U
U + 7 = B
This does not follow the logic.
Hence, option 2 is the odd one out.
