The friends can either get three double rooms or get two triple rooms. Find the minimum amount they will have to pay to accommodate all six of them.

Input Format

  • The first line contains a single integer T - the number of test cases. Then the test cases follow.
  • The first and only line of each test case contains two integers X and Y - the cost of a double room and the cost of a triple room.

Output Format

For each testcase, output the minimum amount required to accommodate all the six friends.

Constraints

  • 1≤T≤100
  • 1≤X<Y≤100

Sample 1:

Input 
3
10 15
6 8
4 8
Output
 
30

12

Solution

#include <iostream>
using namespace std;

int main() {
    int t;
    cin >> t;
    while (t--) {
        int x, y;
        cin >> x >> y;
        int s = x * 3;
        int z = y * 2;
        cout << min(s, z) << endl;
    }
    return 0;
}
