The Farmer's Odd Riddle: A Mathematical Puzzle Explained

When solving riddles and puzzles, we often turn to mathematical equations to find the answer. This engaging puzzle involves a fascinating mix of logical reasoning and basic arithmetic. Let's delve into the riddle and explore how to solve it using algebra.

Setting Up the Equations

The problem presents a unique challenge: a farmer mentions the number of his farm's livestock in a peculiar manner. To decode this, we use variables to represent the number of each type of animal:

Sheep - S Goats - G Horses - H

The farmer’s statements can be translated into mathematical equations:

All sheep bar three means that the total number of animals minus the sheep is three: G H 3 All goats bar four means that the total number of animals minus the goats is four: S H 4 All horses bar five means that the total number of animals minus the horses is five: S G 5

Solving the Equations

Now, we have a system of linear equations:

G H 3 S H 4 S G 5

Let's solve these step by step:

Step 1: Express H in terms of G

From the first equation:

H 3 - G

Step 2: Substitute H into the second equation

Substituting into the second equation:

S (3 - G) 4

This simplifies to:

S - G 1 rarr; S G 1 ldquo;Equation 4rdquo;

Step 3: Substitute S into the third equation

Now substitute Equation 4 into the third equation:

G (1) G 5

This simplifies to:

2G 1 5 rarr; 2G 4 rarr; G 2

Step 4: Find S and H

Now that we have G:

From Equation 4: S G 1 2 1 3 From the first equation: H 3 - G 3 - 2 1

Thus, the farmer has:

3 sheep (S 3) 2 goats (G 2) 1 horse (H 1)

Conclusion

The final counts provide a clear and definitive answer to the riddle. Understanding how to approach and solve such puzzles not only enhances critical thinking skills but also highlights the practical applications of basic algebra in problem-solving.
