Three of the following four letter groups are alike in a certain way and one is different. Choose the odd one out.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → NMKI
Write each letter’s place in the alphabet (A = 1, B = 2, …, Z = 26) and find the jumps from one letter to the next.
Option (1) XWUR — X (24), W (23), U (21), R (18): jumps −1, −2, −3.
Option (2) TSQN — T (20), S (19), Q (17), N (14): jumps −1, −2, −3.
Option (3) ZYWT — Z (26), Y (25), W (23), T (20): jumps −1, −2, −3.
Option (4) NMKI — N (14), M (13), K (11), I (9): jumps −1, −2, −2.
Three groups go −1, −2, −3; NMKI goes −1, −2, −2, so NMKI is the odd one out.
