Ответ:
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
