Problem Analysis

We are given that there are a total of 3320 animals on a farm, including cows, sheep, and goats. We are also given that there are 120 fewer cows than sheep and 100 more cows than goats. We need to determine the number of goats on the farm.

Solution

Let's assume the number of goats on the farm is x.

According to the given information: - The number of cows is 120 less than the number of sheep, so the number of cows is x + 120. - The number of cows is 100 more than the number of goats, so the number of cows is x - 100.

Since we know the total number of animals on the farm is 3320, we can write the equation:

x + (x + 120) + (x - 100) = 3320

Simplifying the equation: 3x + 20 = 3320

Subtracting 20 from both sides: 3x = 3300

Dividing both sides by 3: x = 1100

Therefore, there are 1100 goats on the farm.

Conclusion

The number of goats on the farm is 1100.
