Correct Answer

B. (40)

Step 1

Concept

The sum is ((a+16)+(a+48)+(a+80)=3a+144). From (3a+144=252), (a=36), which is not in the options.

Step 2

Why this answer is correct

The correct answer is B. (40). The sum is ((a+16)+(a+48)+(a+80)=3a+144). From (3a+144=252), (a=36), which is not in the options.

Step 3

Exam Tip

योग ((a+16)+(a+48)+(a+80)=3a+144) है। (3a+144=252) से (a=36) मिलता है जो विकल्पों में नहीं है।
