A person spends $\text{₹ }505$, $\text{₹ }612$, $\text{₹ }256$, and $\text{₹ }365$ in four days. Find the average daily expenditure.

To find the average daily expenditure, we sum up the total expenses and divide by the number of days ($4$ days):
$$\text{Total Expenditure}=505+612+256+365=\text{₹ }1738$$

$$\text{Average Expenditure}=\frac{\text{Total Expenditure}}{\text{Number of Days}}=\frac{1738}{4}=\text{₹ }434.5$$

Therefore, the average daily expenditure is $\text{₹ }434.5$.
