Answer 2

Answer:

87.33 marks

Step-by-step explanation:

First unit test marks = 75 marks              (A)

Second unit test marks = 89 marks        (B)

Third unit test marks = 98 marks            (C)

Average = total numbers in the set / number of items

Here Average = A+B+C / 3

Average = 75 + 89 + 98 / 3

Average = 164 + 98 / 3

Average = 262 / 3

Average = 87.33

The average marks obtained by sandeetha are 87.33
