Detailed Solution
Download Solution PDFGiven:
The number of Horses = The number of Men
The total number of legs walking on the ground = 70
Calculation:
Let, 'X' be the number of horses and 'Y' be the number of men.
Since Horse has 4 legs and a man has 2 legs.
The number of legs walking on the ground is,
⇒ 4X + 2(Y/2) = 70 ----(1)
Y/2 is taken because it is given that Half of the men are on their horses' backs and they are not walking on the ground.
⇒ 4X + Y = 70 ----(2)
As we know,
The number of Horses = The number of Men
⇒ X = Y ----(3)
Therefore, equation (2) becomes,
⇒ 4X + X = 70
⇒ 5X = 70
⇒ X + 70/5
⇒ X = 14
∴ 14 horses and 14 men are there.
