Problem Description

There are at least P% and at most Q% students of HDU are ACMers, now I want to know how many students HDU have at least?

Input

The input contains multiple test cases.
The first line has one integer,represent the number of test cases.
The following N lines each line contains two numbers P and Q(P < Q),which accurate up to 2 decimal places.

Output

For each test case, output the minumal number of students in HDU.

Sample Input

  
   1
13.00 14.10

Sample Output

题意：acmer的人数在P%和Q%之间，最少P%，最多Q%，要求最少有多少个acmer，因为一个数据是最多

一个是最少，所以两个数据的人数不能相同，而且P%一定少于Q%
