a school maintains it's teacher to student ratio as 2:15
1.what will be the number of teachers for 300 students?
2.if there are 20 teachers what is the number of students? ​

Answer 1

Answer:

1. Corresponding to $300$ students there will be $40$ teachers

2. Corresponding to $20$ teachers there will be $150$ students.

Step-by-step explanation:

Given ratio of teachers to students as $2:15$.

Therefore number of teachers $=2x$  ,and

number of students $=15x$.

1. Number of students $=300$, that is $15x=300$

   ⇒$x=20$

  hence number of teachers $=2x=2(20)=40$.

2. Number of teachers $=20$, that is $2x=20$

    ⇒$x=10$

   hence number of students $=15x=15(10)=150$.

Hence the answer
