After taking placement tests, students we removed around changing the ratio of advanced students to the number of regular students to 4: 7.

Answer:

69 students were advanced and 184 were regular

Step-by-step explanation:

begining

advance 3: regular 8

after exam

advance 4 (92students) : regular 7 (92/4=23; 23*7=161 students)

So total students we have 161+92=253,

remember we have advance 3: regular 8 so

253/(3+8)=253/11=23

23*3=69, 23*8=184

69 students were advanced
