/*题意：就是给你两个double的 数据 A B
让你求一个int 数 i 满足 i*A与i*B之间只夹一个数
也就是题目中的ACMER 而此i既是所求的student*/
AC代码：
#include<stdio.h>
#include<string.h>
int main()
{
int i,j,T;
double n,m;
scanf("%d",&T);
while(T--)
{
scanf("%lf %lf",&n,&m);
for(i=1;;i++)
{
if(int(m*i*0.01)-int(n*i*0.01)==1)
break;
}
printf("%d\n",i);
}
return 0;
}
