Problem Statement

The problem consists of two parts: 1. Initially, there were 28 crows, and then some more crows arrived, making the total count 40. 2. In the second scenario, there were some crows, and after 12 more crows arrived, the total count became 40.

Solution

Let's solve the problem step by step.

1. Initial Count of Crows and Additional Arrivals: - Initially: 28 crows - Additional arrivals: Unknown - Total count after additional arrivals: 40 crows

The additional number of crows that arrived can be calculated by subtracting the initial count from the total count: ``` Additional arrivals = Total count - Initial count = 40 - 28 = 12 ```

Therefore, 12 more crows arrived initially to make the total count 40.

2. Second Scenario: - Initially: Unknown - Additional arrivals: 12 crows - Total count after additional arrivals: 40 crows

The initial count of crows can be calculated by subtracting the additional arrivals from the total count: ``` Initial count = Total count - Additional arrivals = 40 - 12 = 28 ```

Therefore, in the second scenario, there were initially 28 crows, and then 12 more crows arrived, making the total count 40.

In conclusion, the initial count of crows in the first scenario was 28, and 12 more crows arrived. In the second scenario, there were initially 28 crows, and then 12 more crows arrived to make the total count 40.
