Correct Answer

A. (144<n<169)

Step 1

Concept

Squaring both sides gives \(12^2<n<13^2\). Therefore (144<n<169) is correct.

Step 2

Why this answer is correct

The correct answer is A. (144<n<169). Squaring both sides gives \(12^2<n<13^2\). Therefore (144<n<169) is correct.

Step 3

Exam Tip

दोनों ओर वर्ग करने पर \(12^2<n<13^2\) मिलेगा। इसलिए (144<n<169) सही है।
