My issue

I am not sure where my logic is going wrong but the commands written in comments is working fine

My code

#include <iostream>
using namespace std;

int main() 
{
    int t;
    cin>>t;
    while(t--)
    {
        int c=0,n;
        cin>>n;
        string a;
        cin>>a;
        for(int i=0;i<n;i++)
        {
        if(a[i]=='1')
        c++;}
        if((c/120)*100>=75|| ((120-n)*100)/120+c/120>=75)
        //int j=120-n+c;
       //float per=(j*100)/120;
      // if(per>=75)
       cout<<"YES"<<endl;
        else
        cout<<"NO"<<endl;
    }
	
	return 0;
}

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--)
	{
	    int n;
	    cin>>n;
	    int cnt=0;
	   string s;
	   cin>>s;
	   for(int i=0;i<n;i++)
	   {
	       if(s[i]=='1')
	       cnt++;
	   }
	   cnt+=(120-n);
	   if(cnt>=90)
	   cout<<"YES";
	   else
	   cout<<"NO";
	   cout<<endl;
	}
	return 0;
}

@dpcoder_007
In your program why have you taken greater than 90
Could also tell me why is my program going wrong

@codestar05
cozz 75% of 120 will be 90 so to have atleast 75% attendance u have to go atleast 90 times.
and U are mistaking it in calculating the percentage of attendance .
