यदि (p(x)=mx+n), (p(-3)=4) और (p(2)=29), तो (m+n) क्या है?
If (p(x)=mx+n), (p(-3)=4) and (p(2)=29), what is (m+n)?
Explanation opens after your attempt
B. (24)
Concept
Subtracting the two values gives (5m=25), so (m=5). Then (-3m+n=4) gives (n=19), so (m+n=24).
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).
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।
