A school has 220 working days. Ravis attendance is 85%. How many days
did he remain absent?

To find how many days Ravi remained absent, we need to calculate 85% of the total 220 working days to determine how many days he attended and then subtract that from the total days.

1. **Step 1:** Calculate the number of days Ravi attended.
\[
85\% \text{ of } 220 = \frac{85}{100} \times 220 = 187 \text{ days}
\]

2. **Step 2:** Subtract the days attended from the total days to find the days he was absent.
\[
220 - 187 = 33 \text{ days}
\]

Therefore, Ravi remained absent for **33 days**.

1. If Ravi's attendance was 90%, how many days would he be absent?
2. How many days would Ravi have attended if the school had 250 working days and his attendance was still 85%?
3. What is the minimum attendance percentage required for Ravi to have attended at least 200 days?
4. If another student had 75% attendance, how many days were they absent in a 220-day school year?
5. How would the calculation change if the school had only 180 working days?

**Tip:** When working with percentages, multiplying the total amount by the percentage (in decimal form) gives the desired portion directly.
