Q153
ReasoningAnalogy, Classification & Odd One Out
Choose the odd one:
  1. a.BdEg
  2. b.KmNp
  3. c.PrSu
  4. d.TwXz

Answer: (D) TwXz

In BdEg, KmNp and PrSu, each successive letter is two places ahead of the previous one in the alphabet (B+2=d, d+2... and so on within each group's pattern). TwXz breaks this consistent pattern, making it the odd one out.
