2. On the written math test, the first problem was not solved by $12 \%$ of the students, $32 \%$ solved it partially, and the remaining 14 students solved it correctly. How many students were in this class?
Solution. The number of students who correctly solved the problem is $100 \%-(32 \%+12 \%)=56 \%$ of the total number of students. Thus, if the class had $x$ students, then $0.56 x=14$, from which we get $x=25$.
