75% of 25 students are good in Maths .Then how many students are not good in maths?

$\huge \mathfrak{ \fcolorbox{green}{red}{\color{yellow}{★Answer}}}$

Given :

75% of 25 students are good in Maths.

To find :

No. of students who are not good in Maths.

Solⁿ :

72% of 25 students

$= > 72\% \times 25 = \frac{72}{ \cancel{100}}\times{ \cancel{ 25}}$

$= > \frac{72}{4} = 18$

$= 18 \: students$

Now,

If 18 students are good in mathematics then no. of students who are not good in mathematics

$Total \: number \: of \: students - No. \: of \: students \: not \: good \: in \: Maths$

$= > 25 - 18 = 7$

$= 7 \: students$

Hence, 7 students are not good in Maths.

Hope it helps...
