At first glance, this puzzle looks simple. We are given the weights of different combinations of animals and asked to determine the weight of a single duck.

The clues are:

Let’s solve it step by step.

A

B

C

ANSWER:

Step 1: Find the weight of one chicken

The first scale shows:

3 chickens = 48 kg

Divide both sides by 3:

1 chicken = 48 ÷ 3 = 16 kg

So:

Chicken = 16 kg

Step 2: Find the weight of the cat

The second scale shows:

Chicken + Cat = 24 kg

Substitute the chicken’s weight:

16 + Cat = 24

Cat = 24 − 16

Cat = 8 kg

So:

Cat = 8 kg

Step 3: Find the weight of two ducks

The third scale shows:

Cat + 2 Ducks = 34 kg

Substitute the cat’s weight:

8 + 2 Ducks = 34

2 Ducks = 34 − 8

2 Ducks = 26 kg

So:

Two ducks weigh 26 kg.

Step 4: Find the weight of one duck

Since two ducks weigh 26 kg:

1 Duck = 26 ÷ 2

1 Duck = 13 kg

Final Answer

The duck weighs 13 kg.
