The more sugar in the syrup, the sweeter it will be. Please use the knowledge of mathematical inequality to solve it.
Let the concentration of raw sugar water be X=a/b, and the added mass m and sugar concentration be Y = (A+M)/(B+M) Y/X = B (A+M)/A (B+M) = (AB+MB)/(AB+AM) AM & GTBM SOAB+MB because of a>. 1 is sweet when the concentration of Y>X is high.
