. Sumit attended his school on 204 days in a full year. If his attendence is 85%, find the number of working days.

To find the total number of working days in the year, we need to set up the relationship based on Sumit's attendance rate. 

Sumit attended school for 204 days, which corresponds to 85% of the total working days. We can represent the total number of working days as \( W \).

Given:
\[ \text{Attendance rate} = 85\% = \frac{85}{100} \]
\[ \text{Days attended} = 204 \]

The relationship can be written as:
\[ \frac{85}{100} \times W = 204 \]

To find \( W \), we need to solve for it:
\[ W = \frac{204 \times 100}{85} \]

Now, let's calculate it:
\[ W = \frac{204 \times 100}{85} \]
\[ W = \frac{20400}{85} \]
\[ W = 240 \]

Therefore, the total number of working days in the year is 240.
