remaining 5 tests total 341 points
6 tests with avg 60 = 360
only needs 19 more points.
That doesn't sound right. If he needs an average of 60 on 7 tests, but one is dropped, does he need an average of 60 on the remaining 6? If so, he's home free. 5 of the first 6 tests had a score of over 60.
Or, does he need a total of 420 points over the 6 exams counted? That means an average of 70. In that case, he needs 79 on the 7th exam.
Poorly worded question.
