Answer 1

Answer:

Step-by-step explanation:

let number of students = x

3/20 of x = 150

x= 150×20/3

 =3000/3

 =1000

therefore, the number of students in the school is 1000

Answer 2

The number of students in the school is 1000.

Step-by-step explanation:

Since we have given that

Part of students ride a bus to the school = $\dfrac{7}{20}$

Part of students are dropped by car = $\dfrac{3}{8}$

Part of students walk to the school = $\dfrac{3}{20}$

Part of students come on their bicycles = $\dfrac{3}{8}$

Let the number of students be 'x'

Number of students coming on foot = 150

According to question, it becomes,

$\dfrac{3}{20}\times x=150\\\\x=\dfrac{150\times 20}{3}\\\\x=50\times 20\\\\x=1000$

Hence, the number of students in the school is 1000.
