include<cstring>
include<string>
include<fstream>
include<sstream>
include<algorithm>
include<vector>
using namespace std;
bool compare( vector<int> x,vector<int> y) {
return x[1] < y[1];
} int main() {
int n, s, a, b;
int count = 0;
vector<vector<int> > xy ;
cin >> n >> s >> a >> b;
for (int i = 0;i < n;i++) {
int xi, yi;
cin >> xi >> yi;
xy.push_back({ xi,yi });
}
sort(xy.begin(), xy.end(), compare);
for (int j = 0;j < n;j++) {
if (s > 0) {
if ((a + b) >= xy[j][0] && (s - xy[j][1] >= 0)) {
count++;
s -= xy[j][1];
}
else if (s - xy[j][1] < 0)
break;
}
}
cout << count;
return 0;
}
