Question

A certain number of horses and an equal number of men are going somewhere. half of the owners are on their horses' 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 ?

Answer 1

Let number of horses = number of men = x.

Then, number of legs
= 4x + 2 x (x/2) = 5x.

So,
5X = 70
x = 14

plzz mark as brainliest answer !!!

Answer 2

Ratio of horses to walking men= 2:1
As horses=2legs, ratio becomes 4:1

Total legs 70. Ratio=4:1. (4+1=5)
70÷5=14. (4*14) (1*14) ⇒ 56 legs of horses, 14 legs of men
No. Of Horses⇒ 56÷4=14
