Practice Test on Operations on Sets
In practice test on operations on sets we will solve 8 different types of questions on more
about sets. The questions will be mainly related to
union of sets
,
intersection of sets
and
difference of sets
.
Practice Test on Operations on Sets
1. If A = {2, 3, 4, 5} B = {4, 5, 6, 7} C = {6, 7, 8, 9} D = {8, 9, 10, 11}, find
(a) A ∪ B
(b) A ∪ C
(c) B ∪ C
(d) B ∪ D
(e) (A ∪ B) ∪ C
(f) A ∪ (B ∪ C)
(g) B ∪ (C ∪ D)
2. If A = {4, 6, 8, 10, 12} B = {8, 10, 12, 14} C = {12, 14, 16} D = {16, 18}, find
(i) (A ∪ D)
∩
(B ∪ C)
3. If A = {4, 7, 10, 13, 16, 19, 22} B = {5, 9, 13, 17, 20}
C = {3, 5, 7, 9, 11, 13, 15, 17} D = {6, 11, 16, 21} then find
