Welcome back to our new town named Errorinous Town. The most characteristics of this town is that people of the town follow a very different Number System for their numerical calculations.

For example, Integer value 36 (lets say) in Normal Number System means "Thirty-Six" , but in
Errorinous Town this will be equal to 63 , i.e, "Sixty-Three".

Akio, a shopkeeper from the town is a very interesting character. She never sells any Product without any Error in the calculation.

She always sells item I of Price P with an Error of E% . This errored price is actual MRP according to Errorinous Town Number System.

But the Price according to Normal Number System will be a different one. And we would like to co-relate the Price of any Item according to Errorinous Town with Normal Number System after the Profit/Lose.

You are given Price of an Item I followed by the Percentage Error E.

Your task is to output the final Price Q of the Item I according to Normal Number System when the Profit/Lose of Price of Item according to Errorinous Town with respect to Normal Number System is added with the Errored Price.

Note : For more explanantion see sample case.

Input : First line will contains an Integer T , number of Test Cases. Next T lines will have two integers P , Price of Item and E , percentage error.

Output : For each Test Case give the output in new line.

Constraints

1 ≤ T ≤25

10 ≤ P ≤ 10000

-70 ≤ E ≤ 70

Important update :  In input you have given a Price P of item and percentage of error E which will effect the selling price for that item. But this is in Errorinous Number System. And the Profit/Lose will be calculated when this price in Actual Number System is co-related with price P in Errorinous Number System. Finally you have to find out the Final Price when this profit/Lose is counted with Errorinous Number System's Errored Price. Final Price is rounded price.

Note : This update in reference with all your queries. Well Done to candidates who solved it.

Explanation

For case 1, Errored Price will be 20,  and Price according to Normal Number System will be 2. There is a Profit of 83.33% when the Price is co-related. So this makes the our final Price Q equal to 37

Update : Final price is according to Errorinous Town Number System. So please calculate in that.
