Student interested in mathematics.

=72%of25

$\frac{72}{100} \times 25$

=18

∴ Student not interested in mathematics

=25−18=7 (Ans)

Answer 2

Step-by-step explanation:

student =72%

total students =25

then per cent used=100

therefore, 72×25÷100

=18

no.of students good in science are 18

total no.of students=25

students not good in science =total no.of students -no.of students good in science

25-18

=7

no.of students interested in science =18
