If "ROME" is coded as "VSQI", what is the code for "GREECE"?

Correct — A.
Rule: every letter moves +4: R→V, O→S, M→Q, E→I.

G→K, R→V, E→I, E→I, C→G, E→I
GREECE → KVIIGI → option (a).

Check: GREECE has E in places 3, 4 and 6, so its code must repeat one letter in those places. KVIIGI is the one option that does.

Why the others are wrong

• (b)
  KVHHFD — KVHHFD moves the first two Es and the C by +3 (E→H, C→F), then turns the last E into D. The given pair moves every letter +4, so each E must become I.
• (c)
  KWHHDF — KWHHDF already fails at letter 2: W is R + 5. ROME's own code shows R → V.
• (d)
  KVIHHD — KVIHHD codes GRE correctly, then gives the second E an H and the last E a D. One rule for every letter means all three Es become I.

In a uniform shift code, every letter moves the same number of places along the alphabet. Read the shift off the given pair one letter at a time: R(18) → V(22) is +4, and O → S, M → Q, E → I confirm it.

Then apply that step to each letter of the new word. A letter that repeats in the word must repeat in its code, which gives a fast check before any counting.

Key facts

• Anchor positions: E5, J10, O15, T20, Y25.
• A uniform shift keeps repeated letters repeated: all three Es of GREECE code to I.
• Past Z, subtract 26: W(23) + 4 = 27 → A(1).

Common traps

• Losing count partway through a six-letter word: option (d) codes GRE correctly and then drifts
• Coding the same letter two different ways, when each E of GREECE must become I
