Answer 2

➡HERE IS YOUR ANSWER⬇

In a class, average score of 50 students is 65.

So, total score = 50 × 65 = 3250

In an another class, average score of 30 students = 30 × 75 = 2250

Total students = 50 + 30 = 80

Total scores = 3250 + 2250 = 5500

Hence, overal score

= (Total score)/(Total students)

= 5500/80

= 68.75
