Question from olwale, a student: a class which consist of 15 boys and 10 girls sit for a test. the average score of the boys is 20 and the girls' is 25. find the average score of the class. |
Hi,
Since the average score for the 15 boys was 20, the sum of the test scores for the boys, divided by 15 is 20. What was the sum of the test scores for the boys? What was the sum of the test scores for the girls? What was the sum of the test scores for the entire class? What was the class average?
