Rješenje:
1. Neka je ukupni iznos koji Ivan ima 180 eura.

2. Potrošnja prvog dana:
- Prvi dan, Ivan potroši trećinu svojih sredstava: \frac{1}{3} \times 180 = 60 eura.
- Preostali iznos nakon prvog dana: 180 - 60 = 120 eura.

3. Potrošnja drugog dana:
- Drugi dan, Ivan potroši 2/5 preostalog iznosa: \frac{2}{5} \times 120 = 48 eura.
- Preostali iznos nakon drugog dana: 120 - 48 = 72 eura.

4. Potrošnja trećeg dana:
- Treći dan, Ivan potroši preostali iznos koji je: 72 eura.

Rješenje: Ivan je treći dan potrošio 72 eura.
