King loves to go on tours with his friends.

King has N cars that can seat 5 people each and M cars that can seat 7 people each. Determine the maximum number of people that can travel together in these cars.

------ Input Format ------

• The first line of input contains a single integer T, the number of test cases.
• The first and only line of each test case contains two space-separated integers N and M — the number of 5-seaters and 7-seaters, respectively.

------ Output Format ------

For each test case, output on a new line the maximum number of people that can travel together.

------ Constraints ------

$1 ≤ T ≤ 100$
$0 ≤ N,M ≤ 100$

----- Sample Input 1 ------
4
4 8
2 13
14 5
8 8
----- Sample Output 1 ------
76
101
105
96
----- explanation 1 ------
Test case $1$: King has $4$ cars that seat $5$ each and $8$ cars that seat $7$ each. So, $4\times 5 + 8\times 7 = 76$ people can travel together.

Test case $2$: King has $2$ cars that seat $5$ each and $13$ cars that seat $7$ each. So, $2\times 5 + 13\times 7 = 101$ people can travel together.

Test case $3$: King has $14$ cars that seat $5$ each and $5$ cars that seat $7$ each. So, $14\times 5 + 7\times 7 = 105$ people can travel together.

Test case $4$: King has $8$ cars that seat $5$ each and $8$ cars that seat $7$ each. So, $8\times 5 + 8\times 7 = 96$ people can travel together.
