Correct Answer

B. (24)

Step 1

Concept

Subtracting the two values gives (5m=25), so (m=5). Then (-3m+n=4) gives (n=19), so (m+n=24).

Step 2

Why this answer is correct

The correct answer is B. (24). Subtracting the two values gives (5m=25), so (m=5). Then (-3m+n=4) gives (n=19), so (m+n=24).

Step 3

Exam Tip

दोनों मान घटाने पर (5m=25) से (m=5) मिलता है। फिर (-3m+n=4) से (n=19), इसलिए (m+n=24) है।
