SSE JE Electrical Engineering 24 March 2021 Shift 2 Paper

Total student = 140
Students do not take part in any of the quiz and Ashu competitions = 16
Students who take part in Quiz and Ashu completion n(∪) = 140 - 16 = 124
Students take part in Quiz n(Q) = 70
Students take part in Ashu competitions n(A) = 77
Students participate in both the quiz and Ashu competition = n(Q ∪ A)
Now;
n(Q∪A) = n(Q) + n(A) - n(Q∩A)
124 = 70 + 77 - (Q∩A)
(Q∩A) = 147 - 124
(Q∩A) = 23
Hence, Students participate in both the quiz and Ashu competition is 23.
