Problem Analysis

In this problem, we are given that there were 5 nests on a birch tree, and each nest had the same number of chicks. After 15 chicks flew away, there were still 15 chicks remaining in the nests. We need to determine how many chicks were initially in each nest.

Solution

Let's assume that there were 'x' chicks in each nest initially. Since there were 5 nests, the total number of chicks initially would be 5 times 'x'.

After 15 chicks flew away, there were still 15 chicks remaining in the nests. This means that the total number of chicks remaining in the nests is equal to the total number of chicks initially minus the 15 chicks that flew away.

Mathematically, we can represent this as:

Total number of chicks remaining = Total number of chicks initially - Number of chicks that flew away

15 = (5 * x) - 15

Now, let's solve this equation to find the value of 'x'.

15 + 15 = 5 * x

30 = 5 * x

Dividing both sides by 5:

6 = x

Therefore, there were initially 6 chicks in each nest.

Answer

There were initially 6 chicks in each nest.
