Four letter clusters have been given in the options, 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: D
Explanation
The correct answer is option 4 i.e. PTXBF.
The logic used here is:
1st letter + 4 = 2nd letter
2nd letter + 3 = 3rd letter
3rd letter + 4 = 4th letter
4th letter + 3 = 5th letter
Option 1: SWZDG
S + 4 = W
W + 3 = Z
Z + 4 = D
D + 3 = G
This follows the logic.
Option 2: JNQUX
J + 4 = N
N + 3 = Q
Q + 4 = U
U + 3 = X
This follows the logic.
Option 3: MQTXA
M + 4 = Q
Q + 3 = T
T + 4 = X
X + 3 = A
This follows the logic.
Option 4: PTXBF
P + 4 = T
T + 3 = W
W + 4 = A
A + 3 = D
This does not follow the logic.
Hence, option 4 is the odd one out.
