यदि (5x-y=19) और (x+y=5) का ग्राफीय समाधान ((p,q)) है, तो (p-q) क्या होगा?
If the graphical solution of (5x-y=19) and (x+y=5) is ((p,q)), what is (p-q)?
Explanation opens after your attempt
Correct Answer
C. (3)
Concept
Solving gives (p=4) and (q=1). Therefore (p-q=3), which comes from the intersection point.
Why this answer is correct
The correct answer is C. (3). Solving gives (p=4) and (q=1). Therefore (p-q=3), which comes from the intersection point.
Exam Tip
हल करने पर (p=4) और (q=1) मिलता है। इसलिए (p-q=3), और यही प्रतिच्छेद से निकला मान है।
