RAS question

AZ : BY :: CX : ?

Correct answer: (B) DW.

In the analogy AZ : BY :: CX : DW, the first letter moves one step forward in the English alphabet and the second letter moves one step backward.

  1. (A)

    DV

  2. (B)

    DW

  3. (C)

    EW

  4. (D)

    DX

Explanation

The rule is positional and consistent across both letters. In AZ to BY, A advances to B while Z retreats to Y. Applying the same rule again gives BY to CX: B advances to C and Y retreats to X. The NCERT-CIIL primer includes an English alphabet table running from A, B, C, D through W, X, Y, Z, which supports these immediate forward and backward letter positions. Therefore, from CX, C must advance one place to D, and X must move one place back to W. The missing pair is DW.

Why the other options are wrong

  • (A) DV keeps the first-letter movement correct as C to D, but moves X back two places instead of one.
  • (C) EW keeps the second-letter movement correct as X to W, but advances C by two places instead of one.
  • (D) DX advances C to D but leaves X unchanged, while the pattern requires the second letter to move one place backward.

Concept

Letter-analogy reasoning identifies a fixed movement rule in alphabet positions and applies it to a new pair. Such questions recur in RAS mental ability because they reward quick pattern extraction without calculation-heavy work.
