Let the total number of students in the class be n. - From condition I, the average marks of the class were 70 . This means the total marks of the class, denoted by T, is:
T=70×n
- From condition II, 10 students scored above the arithmetic mean (average) of the class. This means there are 10 students whose scores are greater than 70 .
Since the total number of students who scored above the average is 10 , and no other information is provided, we can conclude that the number of students who scored more than the average is 10 .
Thus, the correct answer is 2 .
Quick Tip
In problems related to averages and percentages, be sure to differentiate between the total and the group-specific conditions, such as those above or below the mean.
