Ans B. 4:1, for example there are 12 students for every 2 teachers. Now lets increase the number of teachers by 50% which comes out to be 3 teachers. Therefore for every 12 students there are now 3 teachers. Give us 12:3.
After simplifying further we get 4:1. Ans B

Let total number of student and teachers=14m

student=12m
teacher =2m

new teacher=3m (50% increase)

new ratio=12m/3m=4:1

student : teacher
6 : 1

let's assume total no. of student and teacher= 14 ( As we have ratio 6+1=7, total will be the multiple of 7. )

student=12
teacher=2
now , it's given in the question that no. of teachers were to increase by 50%.

now , we have only 2 teachers. 50% of 2 is 1.
so, new no. will be 3.

so new ratio= 12/3=4:1 Note: there were no change in student's no.

So, the correct answer will be B.
