किस मान पर (5x+2y=13) और (10x+4y=k) का कोई समाधान नहीं होगा?
For which value will (5x+2y=13) and (10x+4y=k) have no solution?
Explanation opens after your attempt
B. (k=13)
Concept
The coefficient ratio is \(\frac{1}{2}\); coincidence needs (k=26). For (k=13), the lines are distinct and parallel, so there is no solution.
Why this answer is correct
The correct answer is B. (k=13). The coefficient ratio is \(\frac{1}{2}\); coincidence needs (k=26). For (k=13), the lines are distinct and parallel, so there is no solution.
Exam Tip
गुणांक अनुपात \(\frac{1}{2}\) है; संपाती के लिए (k=26) चाहिए। (k=13) पर रेखाएं समांतर अलग-अलग हैं, इसलिए कोई समाधान नहीं।
