Vijay and Raj want to avoid each other. Vijay is interested in J-type electives and wants to avoid Q-type electives. Raj’s preference is G-type electives followed by Q-type electives. Raj noted that the number of only G-type electives is 2. Is there a possibility that they would not share any common electives(s)?
Explanation:
As y = 2, x has to be 1.
From the answer to the first question of the set, substituting values of y and x in 3z + 2x + y = 13, we get z = 3.
Vijay prefers J-type and avoids Q-type. Raj prefers G-type followed by Q-type.
If Vijay opts for all 7 JG electives or 6JG electives and 1 J-type elective, and Raj opts for 2 G-type and 5 GQ electives or 2 G-type, 4 GQ electives and 1 Q-type electives, they can completely avoid each other.
Hence, option (a).
