Correct Answer
B. (7)
Concept
The key corner is the intersection ((3,4)) of the two slant lines. Checking (x+y) at the corners gives the maximum (7).
Why this answer is correct
The correct answer is B. (7). The key corner is the intersection ((3,4)) of the two slant lines. Checking (x+y) at the corners gives the maximum (7).
Exam Tip
मुख्य कोना दोनों तिरछी रेखाओं का प्रतिच्छेद ((3,4)) है। कोनों पर (x+y) जांचने से अधिकतम (7) मिलता है।
