31 students attended five classes in the month of February for a total of 95 sessions. What was the percentage of classes attended for the month?

Question

I need the overall percentage of classes attended by the 31 students. Students may have attended more than one class for the month and that is where the 95 sessions number comes from. 

Answer 1

The total number of possible sessions that could have been attended is 31*5 = 155, so the percentage that was actually attended is  

 

95/155 ~ 0.6129 = 61.29%
