The ratio between teachers and students has been prescribed as 1:30. If a college has 4620 students, find how many teachers are required in that college for teaching.
Given :
The ratio between teachers and students has been prescribed as 1:30.
The number of students in the college = 4620.
To find :
We have to find the number of teachers required for teaching.
Solution :
Let the number of teachers required for teaching be x.
This implies,
1:30 = x:4620
$ \frac{1}{30} =\frac{x}{4620}$
$ x=\frac{4620\times 1}{30} $ ( Cross multiplication)
$x=154$
Therefore,
The number of teachers required for teaching in that college is 154.
