here my program
what is the problem.
tired of changing it.
WA test#6:

#include <iostream>
#include <cmath>
using namespace std;
int main()
{
    float p,q;
    long long int n=1;
    cin>>p>>q;
    p/=100.0;
    q/=100.0;
    while(ceil(n * q + 1e-9)-ceil(n*p + 1e-9)<1.0)
        n++;
    cout<<n;
    return 0;
}
