Vedclass · Answer

(C) The average score of $15$ girls is $10$. Therefore,the sum of the scores of the girls = $15 	imes 10 = 150$.The average score of $20$ boys is $10$. Therefore,the sum of the scores of the boys = $20 	imes 10 = 200$.The total sum of the scores of all $35$ students = $150 + 200 = 350$.Since we only have the average values,we cannot determine individual scores,such as the highest or lowest scores.Thus,only the sum of the scores of the whole class can be calculated.

In a maths test taken by $35$ students,the average score of $15$ girls is $10$ and that of $20$ boys is also $10$. Which of the following can be calculated based on the data we have?
