+.8%2A75+=+60+ liters of milk in
the 80% solution
Let +x+ = liters of water to be added
--------------------------------------
+60+%2F+%28+x+%2B+75+%29+=+.24+
+60+=+.24%2A%28+x+%2B+75+%29+
+60+=+.24x+%2B+18+
+.24x+=+42+
+x+=+175+
175 liters of water must be added
---------------------------------
check:
+60+%2F+%28+x+%2B+75+%29+=+.24+
+60+%2F+%28+175+%2B+75+%29+=+.24+
+60+%2F+250+=+.24+
+60+=+.24%2A250+
+60+=+60+
OK
