In a certain code, 786 means "study very hard", 958 means "hard work pays", and 645 means "study and work". Which of the following is the code for "very"?
A
8
B
5
C
6
D
7
Correct Option:
D
Explanation
Compare the codes. "786" = study, very, hard. "958" = hard, work, pays. "645" = study, and, work. The common digit between the first two is 8, so 8 = hard. Between the first and third it is 6, so 6 = study. Between the second and third it is 5, so 5 = work. Therefore, the remaining digit 7 = very.
