Chef wants to become fit for which he decided to walk to the office and return home by walking. It is known that Chef’s office is X*X* km away from his home.

If his office is open on 55 days in a week, find the number of kilometers Chef travels through office trips in a week.

- First line will contain T
*T*, number of test cases. Then the test cases follow. - Each test case contains of a single line consisting of single integer X
*X*.

For each test case, output the number of kilometers Chef travels through office trips in a week.

- 1 \leq T \leq 101≤
*T*≤10 - 1 \leq X \leq 101≤
*X*≤10

```
Input:
4
1
3
7
10
Output:
10
30
70
100
```

**Test case 1:** The office is 11 km away. Thus, to go to the office and come back home, Chef has to walk 22 kms in a day. In a week with 55 working days, Chef has to travel 2\cdot 5 = 102⋅5=10 kms in total.

**Test case 2:** The office is 33 kms away. Thus, to go to the office and come back home, Chef has to walk 66 kms in a day. In a week with 55 working days, Chef has to travel 6\cdot 5 = 306⋅5=30 kms in total.

**Test case 3:** The office is 77 kms away. Thus, to go to the office and come back home, Chef has to walk 1414 kms in a day. In a week with 55 working days, Chef has to travel 14\cdot 5 = 7014⋅5=70 kms in total.

**Test case 4:** The office is 1010 kms away. Thus, to go to the office and come back home, Chef has to walk 2020 kms in a day. In a week with 55 working days, Chef has to travel 20\cdot 5 = 10020⋅5=100 kms in total.
