+92+%3C=+%28+95+%2B+98+%2B+92+%2B+x+%29+%2F+4+%3C=+100+
Multiply by +4+
+368+%3C=+95+%2B+98+%2B+92+%2B+x+%3C=+400+
+368+%3C=+285+%2B+x+%3C=+400+
Subtract +285+
+83+%3C=+x+%3C=+115+
Since it's impossible to score +115+, I would say:
+83+%3C=+x+%3C=+100+
Note that it's not possible to average +100+
with the given scores on 3 tests
