यदि (Y(x)=a+7x) रेखीय वृद्धि है और (Y(2)+Y(8)=150), तो (a) क्या है?
If (Y(x)=a+7x) is linear growth and (Y(2)+Y(8)=150), what is (a)?
Explanation opens after your attempt
B. (40)
Concept
(Y(2)+Y(8)=(a+14)+(a+56)=2a+70). From (2a+70=150), (a=40).
Why this answer is correct
The correct answer is B. (40). (Y(2)+Y(8)=(a+14)+(a+56)=2a+70). From (2a+70=150), (a=40).
Exam Tip
(Y(2)+Y(8)=(a+14)+(a+56)=2a+70) है। (2a+70=150) से (a=40) मिलता है।
