=

100

72

×25

=18

∴ Student not interested in mathematics

=25−18=7 (Ans)

Answer 2

${ \underline{ \underline{\huge \bold{AnSwer}}}}$

• percentages of interested students = 72%

➪ percentages of not interested students = 100 + 72 = 28%

so we have to find 28% of 25 students

$\bold{ \implies 28 \times \frac{ \cancel{25}}{ \cancel{100} }} \\ \\ \bold{ \implies{ \cancel{28} \times \frac{1}{ \cancel{4}} }} \: \: \: \: \: \: \\ \\ \bold{ \implies 7} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

so, 28% of 25 students is 7

therefore, there are 7 students are not interested in mathematics.
