Correct Answer

B. (40)

Step 1

Concept

(Y(2)+Y(8)=(a+14)+(a+56)=2a+70). From (2a+70=150), (a=40).

Step 2

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).

Step 3

Exam Tip

(Y(2)+Y(8)=(a+14)+(a+56)=2a+70) है। (2a+70=150) से (a=40) मिलता है।
