Problem Analysis

We are given that a cat and two identical dogs together weigh 10 kg. We are also given that the same cat and one of the dogs weigh 6 kg. We need to determine the weight of each dog and the weight of the cat.

Solution

Let's assume the weight of the cat is C kg and the weight of each dog is D kg.

From the given information, we can form two equations:

Equation 1: C + 2D = 10 (The cat and two dogs together weigh 10 kg)

Equation 2: C + D = 6 (The cat and one of the dogs weigh 6 kg)

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

Subtracting Equation 2 from Equation 1, we get:

(C + 2D) - (C + D) = 10 - 6

Simplifying the equation, we get:

C + 2D - C - D = 4

D = 4

Now, we can substitute the value of D into Equation 2 to find the weight of the cat:

C + 4 = 6

C = 2

Therefore, each dog weighs 4 kg and the cat weighs 2 kg.

Answer

Each dog weighs 4 kg and the cat weighs 2 kg.
