Wrong again: Answer is 95.
If there are x damaged glasses and y undamaged glasses then
x + y = 100
since each glass delivered undamaged is worth 3 points and
each damaged glass deducts 3 points:
and we know that the net result is 90 glasses worth of
points then:
x - y = 90 -----> x = 90 + y
(90 + y) + y = 100
2*y = 10 ---> y = 5
so if number of damaged glasses was 5 then undamaged must
be 100 - 5 = 95
