Answer:Given;
72% of 25 students are interested in mathematics
\therefore Percentage of students not interested in mathematics = (100 - 72)% = 28 %
\therefore The number of students not interested in mathematics = 28% of 25
=\frac{28}{100}\times25 = \frac{28}{4}
= 7
Therefore, 7 students (out of 25) are not interested in mathematics.
