Aman & Mr.Sharma

On a distant planet far away from Earth lives a boy named Aman.He loves to run everyday.But his running distance is directly affected by how much horlicks his mother mixed in his milk today.If his mother has mixed x grams of horlicks,then Aman will be capable of running 100*x meters at most on that day.
Aman's instructor, Mr.Sharma ,is a very strict yet very caring.Everyday he asks Aman to run around a circle of radius r once.If Aman is able to complete the circle,he would get a toffee.
Note:Take value of pie=22/7.
CONSTRAINTS:
1<=d<10⁵
1<=r<10⁶
1<=x<=10⁴
INPUT:
First line contains d,no. of days Aman goes to his instructor.Next d lines each contain r,radius of circle and x,amount of horlicks.
OUTPUT:
Print total number of toffees Aman would finally have at the end of d days.

Solution-

import java.util.*;

class Aman{

    public static void main(String[] args) {

        Scanner sc=new Scanner(System.in);

        int n=sc.nextInt();

        int count=0;

        double a=0;

        double c=0;

        while(n-->0)

        {

            int r=sc.nextInt();

            int h=sc.nextInt();

            a=2*22*r/7;

            c=100*h;

            if(c>=a)

            {

                count++;

            }

            

        }

        System.out.println(count);

    }
