  • Let F1 be the set of parallelograms, F2 the set of rectangles, F3 the set of rhombuses, F4 the set of squares and F5 the set of trapeziums in a plane. Then F1may be equal to (a) F2 intersectioon F3

Let F1 be the set of parallelograms, F2 the set of rectangles, F3 the set of rhombuses, F4 the set of squares and F5 the set of trapeziums in a plane. Then F1may be equal to
(a) F2 ∩F3                                              
(b) F3 ∩F4
(c) F2 u Fs
(d) F2 ∪ F3 ∪ F4 ∪ F1

The answer is the option (d). Rectangles, rhombus and square in a plane is a parallelogram but trapezium is not

F_1 = F_2\cup F_3 \cup F_4 \cup F_1

Hence, (d) is correct
