Chef recently started selling a special fruit.
He has been selling the fruit for X rupees (X is a multiple of 100). He earns a profit of Y rupees on selling the fruit currently.

Chef decided to increase the selling price by 10\%. Please help him calculate his new profit after the increase in selling price.

Note that only the selling price has been increased and the buying price is same.

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

• The first line of input will contain a single integer T, denoting the number of test cases.
• Each test case consists of a single line of input containing two space-separated integers X and Y denoting the initial selling price and the profit respectively.

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

For each test case, output a single integer, denoting the new profit.

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

$1 ≤ T ≤ 1000$
$1 ≤ X ≤ 1000$
$1 ≤ Y ≤ 100$
$X$ is a multiple of $100$.

----- Sample Input 1 ------
4
100 10
200 5
500 10
100 7

----- Sample Output 1 ------
20
25
60
17

----- explanation 1 ------
Test case $1$: The buying price of the item is the difference of selling price and profit, which is $90$. The new selling price is $10\%$ more than the initial selling price. Thus, the new profit is $110-90 = 20$.

Test case $2$: The buying price of the item is the difference of selling price and profit, which is $195$. The new selling price is $10\%$ more than the initial selling price. Thus, the new profit is $220-195 = 25$.

Test case $3$: The buying price of the item is the difference of selling price and profit, which is $490$. The new selling price is $10\%$ more than the initial selling price. Thus, the new profit is $550-490 = 60$.

Test case $4$: The buying price of the item is the difference of selling price and profit, which is $93$. The new selling price is $10\%$ more than the initial selling price. Thus, the new profit is $110-93 = 17$.
