Let +x+ = pounds of sugar to make 25% syrup
+x+%2F+5+=+.25+
+x+=+1.25+
1.25 pounds of sugar, 3.75 pounds of water
--------------------
+x%2F5+=+.75+
+x+=+3.75+
3.75 pounds of sugar, 1.25 pounds of water
--------------------
+x%2F5+=+.015+
you can finish
=====================
Let +x+ = water to be added
+.5%2F%28+x+%2B+.5+%29+=+.2+
+.5+=+.2%2A%28+x+%2B+.5+%29+
+.5+=+.2x+%2B+.1+
+.2x+=+.4+
+x+=+2+
2 pounds of water are needed
