CODECODE - Coder Or NonCoder
The x% of the students in IUT(International University Of Technology) are Coders. Rest of them are noncoders. A new student got admitted into IUT who has lots of interest in programming. So, he wants to meet some senior coders of IUT. As he does not know who is coder and who is not, but he himself is a coder he has y% possibility of identifying a coder. eg. If he meets Zico_vai, He has a y% possibility that he will identify Zico_vai as coder and (100-y)% possibility that he'll mistake. The similar for non coders is also true. eg. If he meets a noncoder he has y% of possibility to identify him as noncoder and (100-y)% possibility that he'll mistake.
Now, He met a random IUTian, given x and y find the probability that he'll think the guy he met as a coder.
Input
First line of the input contains an integer 0 Next t lines contain two integers each x, y (0<=x, y<=100) described above. For each testcase in a new line, print the probability (rounded to 2 digits after decimal point) in percentage with a percentage sign.Output
Example
Input:
2
5 90
12 25
Output:
14.00%
69.00%

"rounded upto 2 digits after decimal point" - rounding to the nearest value should be used (standard rounding used for C/C++ printf will work properly). |
