Hazrat Ali

Codechef

There is a problem worth X points. Chef finds out that the problem has exactly 10 test cases. It is known that each test case is worth the same number of points.

Chef passes N test cases among them. Determine the score Chef will get.

NOTE: See sample explanation for more clarity.

Input Format

  • First line will contain T, number of test cases. Then the test cases follow.
  • Each test case contains of a single line of input, two integers X and N, the total points for the problem and the number of test cases which pass for Chef's solution.

Output Format

For each test case, output the points scored by Chef.

Constraints

  • 1≤T≤100
  • 10≤X≤200
  • 0≤N≤10
  • X is a multiple of 10

Sample 1:

Input 
4
10 3
100 10
130 4
70 0


Output
3
100
52
0

Solution

#include <iostream>
using namespace std;

int main() {
    int T;
    cin >> T;

    while (T--) {
        int X, Y;
        cin >> X >> Y;

        int sum = (X / 10) * Y;
        cout << sum << endl;
    }

    return 0;
}
