Answer 1

$\large{\underline{\red{\rm{AnswEr:280\: students\:50\%}}}}$

$\huge\bold\red{\underline{Solution:}}$

$\bold\green{\underline{Given:}}$

In school

Total number of students=560

Number of students who comes by bicycle=15%

Number of students who comes by the car=17%

Number of students who comes by bus=18%

Number of rest students who comes by walk=X

$\bold\green{\underline{A.T.Q}}$

Sum of the percentage of all students=Total

15+17+18+X=100

50+X=100

X=100-50

X=50%

Now,

Number of students who comes by walk

560×50/100

56×5

280

Hence,

The percentage of students who comes to school by walk is 50%

Total number of students who comes to school by walk is 280

Answer 2

$\huge {\mathfrak {\red{Question :-}}}$

• A school has 560 students. 15% of the students ride a bicycle to school. 17% are driven to school by their parents and 18% catch the bus. The reminder of the students walk to school. What percentage walks and how many students walk?

$\huge{\mathfrak{\pink{Solution :-}}}$

$\underline {\bold {Given :}}$

• Total number of students = 560
• Percentage of students who go to school by bicycle = 15%
• Percentage of students who go to school with their parents = 17%
• Percentage of students who go to school by bus =18%

$\underline {\bold {To\:Find :}}$

• Percentage of students who go to school by walk.
• Number of students who go to school by walk.

To find percentage of students who go to school by walk we first add Percentage of students who go to school by bicycle, Percentage of students who go to school with their parents and Percentage of students who go to school by bus andd then we subtract it from total number of students :

Percentage of students who go to school by walk :

$\longrightarrow [100 - (15 + 17 + 18)]\% \\ \\ \longrightarrow [100 - 50]\% \\ \\ \longrightarrow 50\%$

Now, we find number of students who go to school by walk :

$\longrightarrow 560 \times \frac{50}{100} \\ \\ \longrightarrow 280$

$\green {\tt {\therefore{Percentage \: of \: students \: who \: go\: to \: school \: by \: walk\:is \:50\%.}}}$

$\green {\tt {\therefore{Number \: of \: students \: who \: go\: to \: school \: by \: walk\:is \:280.}}}$
