यदि (n(A)=3x+8), (n(B)=2x+17), (n\(A\cap B\)=x+5) और (n\(A\cup B\)=70) है, तो (x) क्या है?

If (n(A)=3x+8), (n(B)=2x+17), (n\(A\cap B\)=x+5), and (n\(A\cup B\)=70), what is (x)?

Explanation opens after your attempt
Correct Answer

A. (10)

Step 1

Concept

Using the formula, ((3x+8)+(2x+17)-(x+5)=70), so (4x+20=70) and (x=12.5); therefore none of the listed options is correct.

Step 2

Why this answer is correct

The correct answer is A. (10). Using the formula, ((3x+8)+(2x+17)-(x+5)=70), so (4x+20=70) and (x=12.5); therefore none of the listed options is correct.

Step 3

Exam Tip

सूत्र से ((3x+8)+(2x+17)-(x+5)=70), इसलिए (4x+20=70) और (x=12.5) आता है, अतः विकल्पों में कोई सही नहीं।
