यदि (n\(A\cup B\cup C\)=205), (n\(A\cap B\cap C\)=24) और ठीक दो समुच्चयों में (83) तत्व हैं, तो ठीक एक समुच्चय में कितने तत्व हैं?
If (n\(A\cup B\cup C\)=205), (n\(A\cap B\cap C\)=24), and (83) elements are in exactly two sets, how many elements are in exactly one set?
Explanation opens after your attempt
B. (98)
Concept
The union equals exactly one plus exactly two plus all three. Therefore exactly one is (205-83-24=98).
Why this answer is correct
The correct answer is B. (98). The union equals exactly one plus exactly two plus all three. Therefore exactly one is (205-83-24=98).
Exam Tip
संघ (=) ठीक एक (+) ठीक दो (+) तीनों होता है। इसलिए ठीक एक (205-83-24=98)।
