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 1
The correct answer is Option (1) → XZX
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) XZX — X (24), Z (26), X (24): jumps +2, −2.
Option (2) DEC — D (4), E (5), C (3): jumps +1, −2.
Option (3) VWU — V (22), W (23), U (21): jumps +1, −2.
Option (4) FGE — F (6), G (7), E (5): jumps +1, −2.
Three groups go +1, −2; XZX goes +2, −2, so XZX is the odd one out.
