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 3
The correct answer is Option (3) → DHMR
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) DINS — D (4), I (9), N (14), S (19): jumps +5, +5, +5.
Option (2) HMRW — H (8), M (13), R (18), W (23): jumps +5, +5, +5.
Option (3) DHMR — D (4), H (8), M (13), R (18): jumps +4, +5, +5.
Option (4) JOTY — J (10), O (15), T (20), Y (25): jumps +5, +5, +5.
Three groups go +5, +5, +5; DHMR goes +4, +5, +5, so DHMR is the odd one out.
