# Total Expenses Codechef Solution Hello Programmers In this post, you will know how to solve the Total Expenses CodeChef Solution. The Problem Codes is FLOW009.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

### Problem

While purchasing certain items, a discount of 10% is offered if the quantity purchased is more than 1000.

If the quantity and price per item are input, write a program to calculate the total expenses.

### Input

The first line contains an integer T, total number of test cases. Then follow T lines, each line contains integers quantity and price.

### Output

For each test case, output the total expenses while purchasing items, in a new line.

### Constraints

• 1 <= T <= 1000
• 1 <= quantity, price <= 100000

```3
100 120
10 20
1200 20
```

### Output

```12000.000000
200.000000
21600.000000
```

total = 0
m, n = map(int, input().split())
total += (m * n)
if m > 1000:
discount = total - (total * 10/100)
print(discount)
else:
print(total)```
