Answer:
Set A has 7 elements & set B has 8 elements.
Minimum A∪B elements condition: Out of 8 elements of set B, 7 elements are identical to that of set A. In this case A∪B=B & it will have 8 elements.
Maximum A∪B elements condition: A & B are disjoint sets, that no element will be common to them. Then:
n(A∪B)=n(A)+n(B).
A∪B has 15 elements
