You can put this solution on YOUR website!
Let +n+ = number of questions on the test
She got right: +n+-+6+ questions
Her score was:
+%28+n+-+6+%29+%2F+n+=+.76+
+n+-+6+=+.76n+
+n+-+.76n+=+6+
+.24n+=+6+
+n+=+25+
There were 25 questions on the test
-------------
check:
+%28+n+-+6+%29+%2F+n+=+.76+
+%28+25+-+6+%29+%2F+25+=+.76+
+19%2F25+=+.76+
+19+=+.76%2A25+
+19+=+19+
OK
