WORK = 7935, ROCK = 3587 மற்றும் WART = 1945 எனில், T எந்த இலக்கத்தைக் குறிக்கிறது? A. 9 அல்லது 1 B. 8 அல்லது 1 C. 4 அல்லது 5 D. 1 அல்லது 4

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.
