यदि (lx+9y=27) और (8x+18y=55) का कोई हल नहीं है, तो (l) का मान क्या होगा?
If (lx+9y=27) and (8x+18y=55) have no solution, what will be the value of (l)?
Explanation opens after your attempt
C. (4)
Concept
For no solution, (l/8=9/18) and (27/55) must be different. Hence, (l=4).
Why this answer is correct
The correct answer is C. (4). For no solution, (l/8=9/18) and (27/55) must be different. Hence, (l=4).
Exam Tip
कोई हल नहीं के लिए (l/8=9/18) और (27/55) अलग होना चाहिए। इसलिए (l=4)।
