In a given venn-diagram the value of p + q + r is-
 \ (where  n(A∪B∪C)+n(A∪B∪C)′=50)\ \left. \ n(A \cup B \cup C) + n(A \cup B \cup C)^{'} = 50 \right)

Show answer and solution
n(A∪B∪C)+n(A∪B∪C)′=50n(A \cup B \cup C) + n(A \cup B \cup C)^{'} = 50
p + q + r + 10 + 5 + 6 + 8 + 15 = 50

p + q + r = 6
