From the image, we get the scores in Test 2 for all the students

Student A,C - 70
Student B,E - 60
Student D - 80

Therefore, Average of scores in Test 2 is \(\frac{70*2 + 60*2 + 80}{5} = \frac{140 + 200}{5} = \frac{340}{5} = 68\)(Option C)

Dear Moderator,
While going through the coordinate geometry forum found this question. This seems more like a graphs and illustrations problem.Hope you will look into this. Thank you.
