Three of the following test scores are Cyprian's and the other three are Margaret's: 85, 87, 92, 93, 94, 98. Cyprian's mean score is 90. What is Margaret's mean score?

3 of these scores are for Cyprian.

Therefore; 

His scores must add up to 180 for the mean to be 90.

His scores must be 85, 92 and 94.

The remaining values add to 278/3 = 92.6 recurring, round as needed.
