The first-year MBA class at XYZ University is composed of 60 male students and 40 female students. How many male students from the first-year class are taking economics?

Statement (1) Fifty percent of the first-year class is taking economics.

This statement tells us that 50 students from the first-year class are taking economics. Now this could mean 50 male students and 0 female students are taking economics or 10 make students and 40 female students are taking economics. As there are multiple solutions, this statement is not sufficient.

Statement (2) 10 female students from the first-year class are not taking economics.

This tells the number of female students who study economics, but nothing about male students, hence this statement is not sufficient.

Combining both statements, we know total number of first year students taking economics and out of that how many are female students. Therefore we can calculate the number of male students from the first-year class who are taking economics.
