Where does the -1 goes. |

Above method seems to be erroneous. -1 is not accounted. |

Why you have taken 3x150? According to the problem 3x 165. Please explain this. |

Heeee said: (Jun 26, 2014) | |

Where did that - sign went and how that 165 came there? |

Let the expenditure for company X be x. And for company Y be y. Then for co. X- 3x-y/y*100=65. 300x-100y = 65y. 300x =165y. x/y = 165/300. For co. Y 4x-y/y*100 = 50. 400x-100y = 50y. 400x = 150y. Now equal x value to get y value. co. X = (165/300)4 = 660/1200. co. Y = (150/400)3 = 450/1200. Thus we get x:y = 22:15. So answer should be 22:15 not 15:22. |

Prachi said: (Sep 4, 2014) | |

Sorry for wrong answer. 15:22 is correct. For co. X expenditure is 660. For co. Y expenditure is 450. Now co. X/co. Y = 450/660. i.e. 15:22. |

Why am I getting 15/44 --- 3/4*150/165 --- 3/4*30/33 --- 3/4*10/11 --- 30/44? |

3x = 165. 4x = 150. 3x/165*150/4x = 15/22. |

Where did that -1 go? |

Twinkle said: (Jun 27, 2016) | |

Yes, same doubt for me. Where does the - 1 goes? |

Tamilarasan said: (Aug 24, 2016) | |

@All. Taking out the expenditure common the fraction becomes as I/E -1. |

AMBER SINGH said: (Sep 30, 2016) | |

1 is added to 65/100 which then gives us 165/100. |

Lavanya said: (Feb 11, 2017) | |

@Prachi. 450/660=15:22? |

Pema said: (Jul 5, 2018) | |

How the calculation got 3x*100÷165? Explain me in detail. |

Karma Tsh said: (Aug 21, 2021) | |

@Lavanya; 450/660 = 15:22. Ways: 450/15=30, So 30*22 = 660. |
