यदि (n(A)=6x+5), (n(B)=5x+9), (n\(A\cap B\)=3x+4) और (n\(A\cup B\)=106) है, तो (x) का मान क्या है?
If (n(A)=6x+5), (n(B)=5x+9), (n\(A\cap B\)=3x+4) and (n\(A\cup B\)=106), then what is the value of (x)?
Explanation opens after your attempt
A. (12)
Concept
(106=(6x+5)+(5x+9)-(3x+4)=8x+10), so (x=12). In algebraic Venn questions, apply the union formula.
Why this answer is correct
The correct answer is A. (12). (106=(6x+5)+(5x+9)-(3x+4)=8x+10), so (x=12). In algebraic Venn questions, apply the union formula.
Exam Tip
(106=(6x+5)+(5x+9)-(3x+4)=8x+10), इसलिए (x=12) है। बीजगणितीय वेन प्रश्न में संघ का सूत्र लगाएँ।
