Problem Analysis

We are given that a goose is 2 kg heavier than a duck, and a puppy is 3 kg lighter than a goose. We need to determine how much lighter the duck is compared to the puppy.

Solution

Let's assume the weight of the duck is x kg.

According to the given information: - The goose is 2 kg heavier than the duck, so the weight of the goose is x + 2 kg. - The puppy is 3 kg lighter than the goose, so the weight of the puppy is (x + 2) - 3 kg.

To find the difference in weight between the duck and the puppy, we subtract the weight of the puppy from the weight of the duck:

Difference = Weight of Duck - Weight of Puppy

Difference = x - [(x + 2) - 3]

Simplifying the equation:

Difference = x - (x + 2 - 3)

Difference = x - (x - 1)

Difference = x - x + 1

Difference = 1

Therefore, the duck is 1 kg lighter than the puppy.

Answer

The duck is 1 kg lighter than the puppy.
