Question

A certain number of horses and an equal number of men are going somewhere. Half of the owners are on their horses while the remaining ones are walking along leading their horses. If the number of legs walking on the ground is 70, how many horses are there?

• A. 10
• B. 12
• C. 14
• D. 16

Answer 1

Answer: (C)

14

Let there be $x$ horses. Hence, there will be $x$ men.
Then number of legs on the ground = $4x+2\times \frac{x}{2}=70$
$5x=70$
$x=14$
Thus, there are $14$ horses.
