Question

In a public school, the ratio of the number of non-classrooms to the classrooms is 3:17. If the number of non-classrooms is 30, then what is the total number of rooms in the school? ​

Answer 1

Answer:

Step-by-step explanation:

If 30 students are reduced to 3 in ratio that means both the numbers are divided by 10

So the number of classroom students = 17×10 =170

So there are 170 classroom and 30 non-classroom students

Total number of students are 30+170 = 200 students
