यदि (Y(x)=a+10x) रेखीय वृद्धि है और (Y(5)+Y(11)=250), तो (a) क्या है?
If (Y(x)=a+10x) is linear growth and (Y(5)+Y(11)=250), what is (a)?
Explanation opens after your attempt
B. (45)
Concept
(Y(5)+Y(11)=(a+50)+(a+110)=2a+160). From (2a+160=250), (a=45).
Why this answer is correct
The correct answer is B. (45). (Y(5)+Y(11)=(a+50)+(a+110)=2a+160). From (2a+160=250), (a=45).
Exam Tip
(Y(5)+Y(11)=(a+50)+(a+110)=2a+160) है। (2a+160=250) से (a=45) मिलता है।
