यदि (Y(x)=a+9x) रेखीय वृद्धि है और (Y(4)+Y(10)=218), तो (a) क्या है?
If (Y(x)=a+9x) is linear growth and (Y(4)+Y(10)=218), what is (a)?
Explanation opens after your attempt
B. (46)
Concept
(Y(4)+Y(10)=(a+36)+(a+90)=2a+126). From (2a+126=218), (a=46).
Why this answer is correct
The correct answer is B. (46). (Y(4)+Y(10)=(a+36)+(a+90)=2a+126). From (2a+126=218), (a=46).
Exam Tip
(Y(4)+Y(10)=(a+36)+(a+90)=2a+126) है। (2a+126=218) से (a=46) मिलता है।
