A certain number of horses and an equal number of men are going somewhere. Half of the owner are on their horse's back 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 ?

Options

A. 10
B. 10
C. 14
D. 16

Answer

C

Explanation

Let the number of horses = the number of men = x.
Then, the number of legs = `4x + 2 xx x/2 = 5x`
According to the question,
No. of legs = 70 i.e. 5x = 70
or, `x = 70/5 = 14`.
So, required number of horses = x = 14.
