Show answer & explanation
Correct answer: D
Given codes: 134 = good and tasty; 478 = see good pictures; 729 = pictures are faint.
Compare 134 and 478: the common digit is 4, and the only common word is "good"; therefore 4 = good.
Compare 478 and 729: the common digit is 7, and the only common word is "pictures"; therefore 7 = pictures.
Look at 478: the three words are see, good, pictures, and the digits are 4, 7, 8. Since 4 = good and 7 = pictures, the remaining digit 8 must correspond to see.
Answer: 8 stands for "see".
Note: Digits 2 and 9 correspond to "are" and "faint" in 729, but the given information does not tell us which of the two digits maps to which word.
