}
int main()
{
	int t,a[M],b[M],dp[M];
	scanf("%d",&t);
	while(t--)
	{
		int n,v;
		memset(dp,0,sizeof(dp));
		scanf("%d%d",&n,&v);
		for(int i=0;i<n;i++)
		    scanf("%d",&b[i]);
        for(int i=0;i<n;i++)
            scanf("%d",&a[i]);
        for(int i=0;i<n;i++)
        {
        	for(int j=v;j>=a[i];j--)
        	{
	        	dp[j]=max(dp[j],dp[j-a[i]]+b[i]);
	        }
        }
        printf("%d\n",dp[v]);
	}
	return 0;
}
