यदि (Q(t)=420-12t), तो (Q(6)+Q(18)) किस एक (Q(k)) के दोगुने के बराबर है?
If (Q(t)=420-12t), (Q(6)+Q(18)) is equal to twice which (Q(k))?
Explanation opens after your attempt
C. (Q(12))
Concept
In a linear model the midpoint of (6) and (18) is (12). Therefore (Q(6)+Q(18)=2Q(12)).
Why this answer is correct
The correct answer is C. (Q(12)). In a linear model the midpoint of (6) and (18) is (12). Therefore (Q(6)+Q(18)=2Q(12)).
Exam Tip
रेखीय मॉडल में (6) और (18) का मध्य (12) है। इसलिए (Q(6)+Q(18)=2Q(12)) होता है।
