Correct Answer

B. (42)

Step 1

Concept

(Y(3)+Y(9)=(a+24)+(a+72)=2a+96). From (2a+96=180), (a=42).

Step 2

Why this answer is correct

The correct answer is B. (42). (Y(3)+Y(9)=(a+24)+(a+72)=2a+96). From (2a+96=180), (a=42).

Step 3

Exam Tip

(Y(3)+Y(9)=(a+24)+(a+72)=2a+96) है। (2a+96=180) से (a=42) मिलता है।
