Question

Class A has 13 pupils and class B has 16 pupils.

Both classes sit the same maths test.
The mean score for class A is 20.
The mean score for class B is 45.
What is the mean score (rounded to 2 DP) in the maths test across both classes?

Answer 1

ok so we can just add 20 + 45 then divide by 2

20+45=65/2=32.5

32.5

Hope This Helps!!!
