Correct Answer

D. ((4,2))

Step 1

Concept

At ((4,2)), (2x+y=10) and (x+3y=10). Choose the final option only after substituting the point in all inequalities.

Step 2

Why this answer is correct

The correct answer is D. ((4,2)). At ((4,2)), (2x+y=10) and (x+3y=10). Choose the final option only after substituting the point in all inequalities.

Step 3

Exam Tip

((4,2)) पर (2x+y=10) और (x+3y=10) मिलता है। सभी असमानताओं में बिंदु रखकर ही अंतिम विकल्प चुनें।
