You can put this solution on YOUR website!
I can pick any quantity of water
since no quantity is given:
Let +500+ = the quantity of salt and water in the solution ( any units )
+.2%2A500+=+100+ = the quantity of salt in the solution
+400+ = the quantity of water in solution
-------------------------
+400+-+.25%2A400+=+.75%2A400+
+.75%2A400+=+300+
remaining water + salt is:
+300+%2B+100+=+400+
----------------------
+%28+100+%2F+400+%29%2A100+=+25+
The % of salt in new solution is 25%
