Select the option in which the letter-clusters share the same relationship as that shared by the given pair of letter-clusters. GQU : UKG

  • A.ENV : BTR
  • B.PEY : LWC
  • C.WTH : XWM
  • D.QFZ : PEY

Answer: B

The pair that matches the given one is PEY : LWC.

Give the letters their positions: G, Q, U are 7, 17, 21 and the result U, K, G is 21, 11, 7. Each result letter plus its input letter makes 28 (7 + 21, 17 + 11, 21 + 7). Apply the same rule to PEY, which is 16, 5, 25: 28 − 16 = 12 (L), 28 − 5 = 23 (W) and 28 − 25 = 3 (C), giving LWC.

ENV : BTR, WTH : XWM and QFZ : PEY do not give a constant total of 28 for each letter.

This type of question asks for the same relation between letter positions, so test it by adding the positions of each pair. Here every pair adds to 28, equal to 2 × 14, and the pair PEY and LWC fits it letter by letter. The other options give totals that change from letter to letter.
