For each bill you pay using CRED, you earn X CRED coins.  
At CodeChef store, each bag is worth 100 CRED coins. 

Chef pays Y number of bills using CRED. Find the maximum number of bags he can get from the CodeChef store.

------ 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 Y.

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

For each test case, output in a single line - the maximum number of bags Chef can get from the CodeChef store.

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

$1 ≤ T ≤ 100$
$1 ≤ X,Y ≤ 1000$

------ subtasks ------ 

Subtask 1 (100 points): Original constraints.

Test Case $1$: For each bill payment, one receives $10$ CRED coins. Chef pays $10$ bills using CRED. Thus, he receives $100$ CRED coins. Chef can get $1$ bag from the CodeChef store using these coins.

Test Case $2$:  For each bill payment, one receives $20$ CRED coins. Chef pays $4$ bills using CRED. Thus, he receives $80$ CRED coins. Chef cannot get any bag from the CodeChef store using these coins.

Test Case $3$: For each bill payment, one receives $70$ CRED coins. Chef pays $7$ bills using CRED. Thus, he receives $490$ CRED coins. Chef can get at most $4$ bags from the CodeChef store using these coins.
