Problem Analysis

We are given the information that there were ducks, geese, and swans on a farm. The total number of ducks and geese was 260, the total number of geese and swans was 119, and the total number of ducks and swans was 210. We need to determine the number of ducks, geese, and swans separately.

Solution

Let's assume the number of ducks is represented by D, the number of geese is represented by G, and the number of swans is represented by S.

From the given information, we can form the following equations:

1. D + G = 260 (Equation 1) 2. G + S = 119 (Equation 2) 3. D + S = 210 (Equation 3)

To solve this system of equations, we can use substitution or elimination method. Let's use the elimination method.

Adding Equation 1 and Equation 2, we get:

D + G + G + S = 260 + 119

Simplifying, we have:

D + 2G + S = 379 (Equation 4)

Subtracting Equation 3 from Equation 4, we get:

(D + 2G + S) - (D + S) = 379 - 210

Simplifying, we have:

2G = 169

Dividing both sides by 2, we get:

G = 84.5

Since the number of geese cannot be a decimal, we can conclude that there is an error in the given information. Please provide the correct information so that we can assist you further.
