Four brakers = A, B, C & D
One has hard water and soft water in A&B
One has Soap solution and Detergent solution in C & D.
.
Take one braker out of C & D.
Add that solution in A and B.
On shaking the brakers A&B after the solution is added,,If both beakers produce lather , then the solution taken is Detergent out of C or D( Whichever is taken).
If one produce lather and other one produce scum out of A or B.,, then the solution taken is Soap solution and the beaker which produces lather is soft water.,, then other one is hard water...
