Abstract
A puzzle related to biochemistry is presented. There are two compounds, namely, A and B. There is a 40 gram mixture of two of them. The analysis shows that there are 20 grams of A and 20 grams of B. There is no single means of separating them, but a diffraction grating method has been developed. Grating A has the property that it splits any mixture into two portions. Grating B works similarly. The question is that how many gratings are needed to get 10 grams of A in a solution that is 90 percent pure A.
