Remaining 2787

Fifty students took a math test. The average number of points was 68. The top 10 students scored 100 points. What is the average number of points for the remaining 40 students?

Correct answer:

x =  60

Step-by-step explanation:

(10·100+40x)/50 = 68

(10·100+40·x)/50 = 68

40x = 2400

x = 2400/40 = 60

x = 60
