To find:
The number of students not interested in science
Solution:
We will obtain the percentage of students not interested in science by subtracting the percentage of interested students from 100.
The percentage of students not interested in science=100%-72%
=28%
Now, the required number of students=28% of the total students
=28% of 25
=28/100×25
=28/4
=7×4/4
=7
Therefore, the number of students not interested in science is 7.
