If APPLES is written as BORJHP, then how shall BANANA be written as?
  1. a.CZPYQX
  2. b.CZPZQZ
  3. c.CZOZOZ
  4. d.ABLCKD

Answer: (A) CZPYQX

Compare the letters of APPLES and BORJHP position by position: A to B (+1), P to O (-1), P to R (+2), L to J (-2), E to H (+3), S to P (-3). The rule is therefore +1, -1, +2, -2, +3, -3. Applying it to BANANA: B+1 = C, A-1 = Z, N+2 = P, A-2 = Y, N+3 = Q, A-3 = X, giving CZPYQX (A). Options B and C keep Z in several places because they apply only a -1 shift to every A. Tip: write A = 1 to Z = 26 and remember that the alphabet wraps around, so one step back from A is Z.
