InterviewSolution

1.	Let `F_(1)` be the set of parallelograms, `F_(2)` the set of rectangle , `F_(3)` the set of rhombuses, `F_(4)` the set of squares and `F_(5)` the set of trapeziums in a plane. Then, `F_(1)` may be equal toA. `F_(2) nn F_(3)`B. `F_(3) nn F_(4)`C. `F_(2) uu F_(5)`D. `F_(2) uu F_(3) uu F_(4) uu F_(1)`
Answer» Correct Answer - D Every rectangle, rhombus, square in a plane is a parallelogram but every trapezium is not a parallelogram So, `F_(1)` is either of `F_(1), F_(2), F_(3)` and `F_(4)`. `:. F_(1) = F_(2) uu F_(3) uu F_(4) uu F_(1)`
