Class 11 Mathematics Linear Inequalities representation on number line Hard Level 47

यदि (A=(-12,-5]) और (B=[-7,1)), तो संख्या रेखा पर \(A\cap B\) क्या होगा?

If (A=(-12,-5]) and (B=[-7,1)), what is \(A\cap B\) on the number line?

Explanation opens after your attempt
Correct Answer

B. ([-7,-5])

Step 1

Concept

The common part is from (-7) to (-5), and both endpoints are included. In exams, choose only the overlapping segment for intersection.

Step 2

Why this answer is correct

The correct answer is B. ([-7,-5]). The common part is from (-7) to (-5), and both endpoints are included. In exams, choose only the overlapping segment for intersection.

Step 3

Exam Tip

साझा भाग (-7) से (-5) तक है और दोनों सिरे शामिल हैं। परीक्षा में intersection में केवल overlapping segment चुनें।
