Solve the programming task below in a Python markdown code block.
Chef's current age is 20 years, while Chefina's current age is 10 years.  
Determine Chefina's age when Chef will be X years old.

Note: Assume that Chef and Chefina were born on same day and same month (just different year).

------ 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 integer X, the age of Chef.

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

For each test case, output Chefina's age when Chef will be X years old.

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

$1 ≤ T ≤ 25$
$25 ≤ X ≤ 50$

----- Sample Input 1 ------ 
4
25
36
50
44

----- Sample Output 1 ------ 
15
26
40
34

----- explanation 1 ------ 
Test case $1$: Chefina is $10$ years old when Chef is $20$ years old. Thus, when Chef would be $25$, Chefina would be $15$.

Test case $2$: Chefina is $10$ years old when Chef is $20$ years old. Thus, when Chef would be $36$, Chefina would be $26$.

Test case $3$: Chefina is $10$ years old when Chef is $20$ years old. Thus, when Chef would be $50$, Chefina would be $40$.

Test case $4$: Chefina is $10$ years old when Chef is $20$ years old. Thus, when Chef would be $44$, Chefina would be $34$.
