Question 1/2 Hard Mathematics Sets Venn Diagrams Class 11 Level 14

यदि (n(A-B)=x), (n(B-A)=3x), (n\(A\cap B\)=24) और (n\(A\cup B\)=120) है, तो (x) कितना है?

If (n(A-B)=x), (n(B-A)=3x), (n\(A\cap B\)=24), and (n\(A\cup B\)=120), what is (x)?

Explanation opens after your attempt
Correct Answer

B. (24)

Step 1

Concept

From the union regions, (x+3x+24=120), so (4x=96) and (x=24). Solve unknown regions by forming an equation.

Step 2

Why this answer is correct

The correct answer is B. (24). From the union regions, (x+3x+24=120), so (4x=96) and (x=24). Solve unknown regions by forming an equation.

Step 3

Exam Tip

संघ के भागों से (x+3x+24=120), इसलिए (4x=96) और (x=24)। अज्ञात क्षेत्र को समीकरण से हल करें।

Question 2/2 Hard Mathematics Sets Venn Diagrams Class 11 Level 13

यदि (n(A-B)=x), (n(B-A)=2x), (n\(A\cap B\)=15) और (n\(A\cup B\)=75) है, तो (x) कितना है?

If (n(A-B)=x), (n(B-A)=2x), (n\(A\cap B\)=15), and (n\(A\cup B\)=75), what is (x)?

Explanation opens after your attempt
Correct Answer

B. (20)

Step 1

Concept

From the union regions, (x+2x+15=75), so (3x=60) and (x=20). Solve unknown regions by forming an equation.

Step 2

Why this answer is correct

The correct answer is B. (20). From the union regions, (x+2x+15=75), so (3x=60) and (x=20). Solve unknown regions by forming an equation.

Step 3

Exam Tip

संघ के भागों से (x+2x+15=75), इसलिए (3x=60) और (x=20)। अज्ञात क्षेत्र को समीकरण से हल करें।
