If WORK = 7935, ROCK = 3587 AND WART = 1945, which digit stands for T? A. Either 9 or 1 B. Either 8 or 1 C. Either 4 or 5 D. Either 1 or 4

  1. B

  2. C

  3. A

  4. D

Show answer & explanation

Answer: (D) D

Explanation

WORK and ROCK share O, R and K, and their codes share 3, 5 and 7, so W = 9 and C = 8. WART = 1945 contains W (9) and R; the only digit for R common to both is 5. That leaves A and T as 1 and 4 in some order, so T is either 1 or 4.
