Question
Sets A, B, C and D are all subsets of quadrilaterals. A is the set of rhombi, B is the set of rectangles, C is the set of parallelograms, and D is the set of kites. What is the set (A∩B)∪(C∩D)?
Answer: Option D
:
D
Soln:
A∩B is a set of quadrilaterals that are both rhombi and rectangles - which are squares. C∩D is a set of quadrilaterals that are both parallelograms and kites - which are rhombi. Finally, the union of squares and rhombi are... rhombi. Hence option (d)
