यदि (n(U)=110) और (n\(A\cup B\cup C\)=92) है, तो किसी भी समुच्चय में नहीं आने वाले तत्व कितने हैं?
If (n(U)=110) and (n\(A\cup B\cup C\)=92), how many elements are in none of the sets?

B. (18)
Concept
None is (110-92=18). The outside region is found by subtracting the union from (U).
Why this answer is correct
The correct answer is B. (18). None is (110-92=18). The outside region is found by subtracting the union from (U).
Exam Tip
किसी में नहीं (110-92=18) है। बाहर का क्षेत्र (U) से संघ घटाकर मिलता है।
