Answer 1

I believe the answer is 90.6

Explanation:

I added 200+900+240+70+855 and got 2,265. If I divide that by 25 I get 90.6.

Hope this helps!

Answer 2

Answer with Step-by-step explanation:

A class of 25 students took a spelling test.

Number of students Marks obtained

2 100

9 95

10 90

3 80

1 70

Average marks=sum of marks/number of students

Sum of marks=100×2+9×95+10×90+3×80+70×1

=2265

Number of students=25

Average=2265/25

=90.6

Hence, average score of the spelling test rounded to one decimal place is:

90.6
