Q102
ReasoningAnalogy, Classification & Odd One Out
Fill in the missing letter in the following series: S, V, Y, B, ?
  1. a.C
  2. b.D
  3. c.E
  4. d.G

Answer: (C) E

The pattern: S(+3)→V(+3)→Y(+3)→B(+3)→E. Each letter advances by 3 positions in the alphabet (treating it as circular: after Z comes A). Y + 3 = B (treating Z as 26, A as 1: Y=25, +3=28−26=2=B), then B + 3 = E.
