Total score 30 x 75 = 2250, male total 20 x 70 ie 1400, so 10 females scored total of 850, an average of 85.
You would first multiply 35 x 18 to find out how many total students there are, which is 630. Then, you would divide 630/30, since you can only have 30 students maximum in a class. This gives you the answer of 21 classes must be formed.
