Janmansh received X coins of 10 rupees and Y coins of 5 rupees from Chingari. Since he is weak in math, can you find out how much total money does he have?

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

- The first line will contain T - the number of test cases. Then the test cases follow.
- The first and only line of each test case contains two integers X, Y - the number of 10 and 5 rupee coins respectively.

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

For each test case, output how much total money does Janmansh have.

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

$1 ≤T ≤100$
$0 ≤X, Y ≤100$

----- Sample Input 1 ------ 
2
2 1
3 4

----- Sample Output 1 ------ 
25
50

----- explanation 1 ------ 
Test case-1: He has $2$ coins of $10$ rupees and $1$ coin of $5$ rupees. Hence he has $2 \cdot 10+5 = 25$ rupees.

Test case-2: He has $3$ coins of $10$ rupees and $4$ coins of $5$ rupees. Hence he has $3 \cdot 10 + 4 \cdot 5 = 50$ rupees.
