Question

In a stable, the number of legs of horses are 48. How many ears of horses are there in the stable?

Answer 1

We know that each horse has 4 legs, so the number of horses in the stable = 48 $÷$ 4

$$\begin{array}{c}12\\ 448\\ -\underset{–}{4}2\\ 08\\ -\underset{–}{08}\\ 0\end{array}$$
Each horse has two ears, so the total number of horse ears in the stable = 12 x 2
= 24.
