Question

The table below shows the test scores (out of 100) of two students in three tests:

| Student   | Test 1 | Test 2 | Test 3 |
|-----------|--------|--------|--------|
| Student X | 82     | 78     | 85     |
| Student Y | 88     | 86     | 90     |

**Question:** Which student had a higher average score?

Accepted Answer

Solution:
Student X scores are:
$$ 82,\ 78,\ 85 $$
Average score of Student X:
$$ \frac{82 + 78 + 85}{3} $$
$$ = \frac{245}{3} $$
$$ = 81.67 $$
Student Y scores are:
$$ 88,\ 86,\ 90 $$
Average score of Student Y:
$$ \frac{88 + 86 + 90}{3} $$
$$ = \frac{264}{3} $$
$$ = 88 $$
Since:
$$ 88 > 81.67 $$
Student Y had the higher average score.
Final Answer: **(b) Student Y**
