Can't find practice questions for this topic because I don't exactly know what this topic is actually called.
25 students in class A did a science exam.30 students in class B did the same science exam.The mean mark for the 25 students in class A is 67.8The mean mark for all the 55 students is 72.0Work out the mean mark for the students in class B.
I thought it went under "averages: mean" but I just end up finding questions that ask about the mean from a table or set of data which isn't what I'm looking for.

It is just averages applied to a slightly different scenario.

This question is a about understanding the mean in the "Robin Hood" sense of sharing the available numbers equally. It is however still just about the mean.
