Problem Description

There are 2 cages, each containing crested cockatoos and cockatiels. In the first cage there are 67 birds total. In the second cage there are 6 fewer crested cockatoos and 8 more cockatiels. The question is: how many birds are in the second cage?

Breaking Down the Information

The first cage contains 67 birds total. The second cage contains 6 fewer crested cockatoos. The second cage contains 8 more cockatiels.

Solving the Problem

Let's call: C1 = number of crested cockatoos in first cage C2 = number of crested cockatoos in second cage T1 = number of cockatiels in first cage T2 = number of cockatiels in second cage

We know: C1 + T1 = 67 (total birds in first cage) C2 = C1 - 6 (6 fewer crested cockatoos in second cage) T2 = T1 + 8 (8 more cockatiels in second cage)

Substituting C2 = C1 - 6 into the first equation: C1 + T1 = 67 C1 - 6 + T1 = ?

Solving this: C1 + T1 - C1 + 6 + T1 = 67 2T1 + 6 = 67 2T1 = 61 T1 = 30.5 Rounding down, T1 is 30 cockatiels

Therefore: C1 is 67 - 30 = 37 crested cockatoos C2 is 37 - 6 = 31 crested cockatoos T2 is 30 + 8 = 38 cockatiels

Total birds in second cage is 31 + 38 = 69

So the number of birds in the second cage is 69.
