एक सर्वे में (n(U)=260), (n(A)=118), (n(B)=104), (n(C)=92), (n\(A\cap B\)=48), (n\(B\cap C\)=41), (n\(C\cap A\)=37) और (n\(A\cap B\cap C\)=16) हैं। किसी भी समुच्चय में नहीं आने वाले कितने हैं?

In a survey (n(U)=260), (n(A)=118), (n(B)=104), (n(C)=92), (n\(A\cap B\)=48), (n\(B\cap C\)=41), (n\(C\cap A\)=37), and (n\(A\cap B\cap C\)=16). How many are in none of the sets?

Correct Answer

B. (56)

Step 1

Concept

The union is (118+104+92-48-41-37+16=204), so none is (260-204=56). First find the three-set union.

Step 2

Why this answer is correct

The correct answer is B. (56). The union is (118+104+92-48-41-37+16=204), so none is (260-204=56). First find the three-set union.

Step 3

Exam Tip

संघ (118+104+92-48-41-37+16=204) है, इसलिए कोई नहीं (260-204=56)। पहले तीन-समुच्चय संघ निकालें।
