R – Sugarcane Juice Business

While Alice was drinking sugarcane juice, she started wondering about the following facts:

• The juicer sells each glass of sugarcane juice for 5050 coins.
• He spends 20%20% of his total income on buying sugarcane.
• He spends 20%20% of his total income on buying salt and mint leaves.
• He spends 30%30% of his total income on shop rent.

Alice wonders, what is the juicer’s profit (in coins) when he sells 𝑁N glasses of sugarcane juice?

Input Format

• The first line of input will contain an integer 𝑇T — the number of test cases. The description of 𝑇T test cases follows.
• The first and only line of each test case contains an integer 𝑁N, as described in the problem statement.

Output Format

For each test case, output on a new line the juicer’s profit when he sells 𝑁N glasses of juice.

Constraints

• 1≤𝑇≤10001≤T≤1000
• 1≤𝑁≤1061≤N≤106

Test case 11: The total income is 50×2=10050×2=100 coins. The juicer spends 2020 coins on sugarcane, 2020 coins on salt and mint leaves and 3030 coins on rent. Thus, the profit is 100−(20+20+30)=30100−(20+20+30)=30 coins.

Test case 22: The total income is 50×4=20050×4=200 coins. The juicer spends 4040 coins on sugarcane, 4040 coins on salt and mint leaves and 6060 coins on rent. Thus, the profit is 200−(40+40+60)=60200−(40+40+60)=60 coins.

Test case 33: The total income is 50×5=25050×5=250 coins. The juicer spends 5050 coins on sugarcane, 5050 coins on salt and mint leaves and 7575 coins on rent. Thus, the profit is 250−(50+50+75)=75250−(50+50+75)=75 coins.

Test case 44: The total income is 50×10=50050×10=500 coins. The juicer spends 100100 coins on sugarcane, 100100 coins on salt and mint leaves and 150150 coins on rent. Thus, the profit is 500−(100+100+150)=150500−(100+100+150)=150 coins.
