यदि (P(t)=42+6t), तो (P(3)+P(11)) किस एक (P(k)) के दोगुने के बराबर है?
If (P(t)=42+6t), (P(3)+P(11)) is equal to twice which (P(k))?
Explanation opens after your attempt
C. (P(7))
Concept
In a linear model the midpoint of (3) and (11) is (7). Therefore (P(3)+P(11)=2P(7)).
Why this answer is correct
The correct answer is C. (P(7)). In a linear model the midpoint of (3) and (11) is (7). Therefore (P(3)+P(11)=2P(7)).
Exam Tip
रेखीय मॉडल में (3) और (11) का मध्य (7) है। इसलिए (P(3)+P(11)=2P(7)) होता है।
