Why we multiply by x/2? |

Because half a man is in horses back, thats why multiply by x/2. |

Why we multiply by 4x? |

How this 5x came? |

See totally 70 legs. 1. Horses totally have a 4 legs. 2. Humans totally have a 2 legs. So 4x + (2*x) /2. That the simple reason. |

The total num of legs comes as: Horses legs is 4 * number of horses = 4*(x). Humans leg is 2 * number of humans i.e. half of the humans, x/2 = 2*(x/2). So total number of legs are : (4*x) + (2*(x/2)) = 5x. So, we get 5x = 70. |

Here it should be, 4X + (2X)/2 = 4X + 1X =5X is correct. |

4x+2x/2=70. 8x+2x/2=70, 10x/2=70, 70*2/10= 14. |

@Ganesh. Why half of the humans, why not half of the horses. |

Sherab said: (Apr 3, 2022) | |

Here no Of horses and men is equal. So, Let's say x While half of the owner is on horses back and a half walking So total legs on the ground is 70. We know a horse has 4 legs and a man has 2 legs So 4x + 2(x/2)= 70 (here x/2 is bcoz half of the men is on horse's back while only half is walking with horses). 5x = 70 . x = 14 (horses and men). |
