यदि (P(t)=75+6t), तो (P(6)+P(18)) किस एक (P(k)) के दोगुने के बराबर है?
If (P(t)=75+6t), (P(6)+P(18)) is equal to twice which (P(k))?
Explanation opens after your attempt
C. (P(12))
Concept
In a linear model the midpoint of (6) and (18) is (12). Therefore (P(6)+P(18)=2P(12)).
Why this answer is correct
The correct answer is C. (P(12)). In a linear model the midpoint of (6) and (18) is (12). Therefore (P(6)+P(18)=2P(12)).
Exam Tip
रेखीय मॉडल में (6) और (18) का मध्य (12) है। इसलिए (P(6)+P(18)=2P(12)) होता है।
