Correct Answer

C. अनंत अनेक हलInfinitely many solutions

Step 1

Concept

The second equation is \(\frac{3}{2}\) times the first, so both represent the same line. In exams, if all ratios are equal, there are infinitely many solutions.

Step 2

Why this answer is correct

The correct answer is C. अनंत अनेक हल / Infinitely many solutions. The second equation is \(\frac{3}{2}\) times the first, so both represent the same line. In exams, if all ratios are equal, there are infinitely many solutions.

Step 3

Exam Tip

दूसरा समीकरण पहले का \(\frac{3}{2}\) गुना है, इसलिए दोनों समान रेखा दर्शाते हैं। परीक्षा में सभी अनुपात बराबर हों तो अनंत हल होते हैं।
