1. The problem states that Hassan earns 3500 in 5 days. 2. We need to find his earning for one day. 3. To find the daily earning, divide the total earning by the number of days: $$\text{Daily earning} = \frac{3500}{5}$$ 4. Calculate the division: $$\frac{3500}{5} = 700$$ 5. Therefore, Hassan earns 700 per day.
