The bacteria in a culture grows by 10% in the first hour, decreases by 10% in the second hour and again increases by 10% in the third hour. If the original count of the bacteria in a sample is 10000, find the bacteria count at the end of 3 hours.

Explanation

To find the bacteria count at the end of 3 hours, we will calculate the count step by step based on the growth and decrease rates provided.

### Step 1: Calculate the count after the first hour
The bacteria grow by 10% in the first hour.

- **Original count** = 10000
- **Increase** = 10% of 10000 = (10/100) * 10000 = 1000
