Q. If set A contains 10 elements, set B contains 15 elements, and the intersection of A and B contains 5 elements, what is the number of elements in the union of sets A and B?
A.
20
B.
15
C.
10
D.
5
Solution
The number of elements in the union of sets A and B is given by |A ∪ B| = |A| + |B| - |A ∩ B| = 10 + 15 - 5 = 20.

Q. In a group of 50 people, 30 like reading fiction, 20 like reading non-fiction, and 5 like both. How many people do not like reading?
A.
15
B.
20
C.
