यदि (Y(x)=a+5x) रेखीय वृद्धि है और (Y(2)+Y(6)=86), तो (a) क्या है?
If (Y(x)=a+5x) is linear growth and (Y(2)+Y(6)=86), what is (a)?
Explanation opens after your attempt
B. (23)
Concept
(Y(2)+Y(6)=(a+10)+(a+30)=2a+40). From (2a+40=86), (a=23).
Why this answer is correct
The correct answer is B. (23). (Y(2)+Y(6)=(a+10)+(a+30)=2a+40). From (2a+40=86), (a=23).
Exam Tip
(Y(2)+Y(6)=(a+10)+(a+30)=2a+40) है। (2a+40=86) से (a=23) मिलता है।
