If FRANCE is coded as 654321 and GERMANY is coded as 9158437, then how is YEMEN coded?
Answer & explanation
Answer: (d) 71813
Each letter keeps a fixed digit across both words: Y = 7, E = 1, M = 8 and N = 3. So YEMEN is 7-1-8-1-3, i.e. 71813.
- From FRANCE = 654321: F = 6, R = 5, A = 4, N = 3, C = 2, E = 1.
- From GERMANY = 9158437: G = 9, E = 1, R = 5, M = 8, A = 4, N = 3, Y = 7 (E, R, A, N agree with the first word).
- YEMEN = Y, E, M, E, N = 7, 1, 8, 1, 3 = 71813.
Remember · For letter-to-digit codes, build a lookup table from the given words and read off the new word; check shared letters agree.
