Answer 1

4 pesas de 1 kg + 1 pesa de 5 kg + 4 pesas de 10 kg = 9 pesas

1 kg = 1 kg
2 kg = 1 kg + 1 kg
3 kg = 1 kg + 1 kg + 1 kg
4 kg = 1 kg + 1 kg + 1 kg + 1 kg
5 kg = 5 kg
6 kg = 5 kg + 1 kg
7 kg = 5 kg + 1 kg + 1 kg
8 kg = 5 kg + 1 kg + 1 kg + 1 kg
9 kg = 5 kg + 1 kg + 1 kg + 1 kg + 1 kg
10 kg = 10 kg
11 kg = 10 kg + 1 kg
12 kg = 10 kg + 1 kg + 1 kg
13 kg = 10 kg + 1 kg + 1 kg + 1 kg
14 kg = 10 kg + 1 kg + 1 kg + 1 kg + 1 kg
15 kg = 10 kg + 5 kg
16 kg = 10 kg + 5 kg + 1 kg
17 kg = 10 kg + 5 kg + 1 kg + 1 kg
18 kg = 10 kg + 5 kg + 1 kg + 1 kg + 1 kg
19 kg = 10 kg + 5 kg + 1 kg + 1 kg + 1 kg + 1 kg
20 kg = 10 kg + 10 kg
21 kg = 10 kg + 10 kg + 1 kg
22 kg = 10 kg + 10 kg + 1 kg + 1 kg
23 kg = 10 kg + 10 kg + 1 kg + 1 kg + 1 kg
24 kg = 10 kg + 10 kg + 1 kg + 1 kg + 1 kg + 1 kg
25 kg = 10 kg + 10 kg + 5 kg
26 kg = 10 kg + 10 kg + 5 kg + 1 kg
27 kg = 10 kg + 10 kg + 5 kg + 1 kg + 1 kg
28 kg = 10 kg + 10 kg + 5 kg + 1 kg + 1 kg + 1 kg
29 kg = 10 kg + 10 kg + 5 kg + 1 kg + 1 kg +1 kg + 1 kg
30 kg = 10 kg + 10 kg + 10 kg
31 kg = 10 kg + 10 kg + 10 kg + 1 kg
32 kg = 10 kg + 10 kg + 10 kg + 1 kg + 1 kg
33 kg = 10 kg + 10 kg + 10 kg + 1 kg + 1 kg + 1 kg
34 kg = 10 kg + 10 kg + 10 kg + 1 kg + 1 kg + 1 kg + 1 kg
35 kg = 10 kg + 10 kg + 10 kg + 5 kg
36 kg = 10 kg + 10 kg + 10 kg + 5 kg + 1 kg
37 kg = 10 kg + 10 kg + 10 kg + 5 kg + 1 kg + 1 kg
38 kg = 10 kg + 10 kg + 10 kg + 5 kg + 1 kg + 1 kg + 1 kg
39 kg = 10 kg + 10 kg + 10 kg + 5 kg + 1 kg + 1 kg + 1 kg + 1 kg
40 kg = 10 kg + 10 kg + 10 kg + 10 kg
