Let +x+ = number in the class
+7+ don't like basketball
+x+-+7+ like basketball
-------------------------
You are given that:
+%28+3%2F4+%29%2Ax+=+x+-+7+
+3x+=+4x+-+28+
+x+=+28+
There are 28 in the class
----------------------
check:
+%283%2F4%29%2A28+=+21+ like basketball
+7+ don't like basketball
+21+%2B+7+=+28+
OK
