Question

72% of 25 students are interested in mathematics how many are not interested in mathematics​

Answer 1

Answer:

\textbf{Given:}Given:

\mathsf{72\%\;of\;25\;students\;are \;interested\;in\;mathematics}72%of25studentsareinterestedinmathematics

\textbf{To find:}To find:

\textsf{How many students are not interested in mathematics}How many students are not interested in mathematics

\textbf{Solution:}Solution:

\textsf{Total number of students =25}Total number of students =25

\mathsf{Percentage\;of\;students \;interested\;in\;Mathematics=72\%}PercentageofstudentsinterestedinMathematics=72%

\textsf{Percentage of students not interested in Mathematics=100\%-72\%=28\%}Percentage of students not interested in Mathematics=100%-72%=28%

\mathsf{Number\;of\;students\;not\;interested\;in\;mathematics}Numberofstudentsnotinterestedinmathematics

\mathsf{=28\%\;of\;25}=28%of25

\mathsf{=\dfrac{28}{100}{\times}25}=

Answer 2

Answer:

7 students are not interested in mathematics

Step-by-step explanation:

$\purple{ \mathfrak{ \underbrace{solution}}}$

If, 100% equals 25 students,

Then,

$100\% = 25 \\ 1\% = \frac{25}{100} \\ 72\% = \frac{25 \times 72}{100} = 18$

Hence, 18 students are interested in mathematics

Students are not interested in mathematics are(25-18)=7
