The total of test scores of 100 students is 7,800. Find the average score of a student.

• A. 78.00
• B. 780
• C. 7.8
• D. 7800

Answer 1

The correct option is A 78.00

Total test scores of 100 students = 7,800

Average test score = 7800.00 $÷$ 100

To divide a number by 100, we have to move the decimal point two places to the left.

$⟹$ 7800.00 $÷$ 100 = 78.00

Hence, the average test score = 78.00
