## Python Basic - 1: Exercise-21 with Solution

Write a Python program to find the number of notes (Samples of notes: 10, 20, 50, 100, 200, 500) against an amount.

Range - Number of notes(n) : n (1 ≤ n ≤ 1000000).

**Pictorial Presentation:**

**Sample Solution**:

**Python Code:**

```
def no_notes(a):
Q = [500, 200, 100, 50, 20, 10]
x = 0
for i in range(6):
q = Q[i]
x += int(a / q)
a = int(a % q)
if a > 0:
x = -1
return x
print(no_notes(880))
print(no_notes(1000))
```

Sample Output:

6 2
