JEE Main 17 March 2021, Shift 1, Maths Q61

Question 61 of 90 in this shift, Maths question 1 of 30, Section A.

In a school, there are three types of games to be played. Some of the students play two types of games, but none play all the three games. Which Venn diagrams can justify the above statement ?

The figure, in words

Three Venn diagrams labelled P, Q, R below the stem (labels printed). Each is made of one large circle and two smaller circles that overlap each other. P: both smaller circles lie entirely inside the large circle and overlap each other. Q: the two smaller circles overlap each other and each also overlaps the large circle, extending partly outside it (left one out to the left, right one out to the right). R: the left smaller circle extends partly outside the large circle on the left and overlaps it; the right, smaller circle lies inside the large circle and overlaps the left smaller circle.
