I would like to understand that what is actual method to calculate ratio, Here I would like to add that 21*24700/14*27300 = to come different figure. So please let me know that should be ideally calculated? |

How or what quick method can we use or know that it is 273 that will divide 5187 and 3822 to give us 19:14. Quickest way of solving ratio? |

Divide 5187 and 3822 by 3 you will get 1729 and 1274. Then add units of each number i.e.,1+7+2+9 = 19 and 1+2+7+4 = 14. Thus Ratio between PG and Grad of institute S is 19:14. |

Please explain way to calculate the ratios in more detail. |

24700 * 21/100 : 27300 * 14/100 = 19 : 14. |

From where you take this 5187 and 3822 values? Explain clearly. |

@ GOPAL, SARIKA & MANISHA. P.G from Institute S = 24700*(21/100) = 247*21 = 5187. Grad. from institute S = 27300*(14/100) = 273*14 = 3822. P.G./Graduate = 5187/3822 {DIVIDE 5187 & 3822 BY 3} = 1729/1274 {DIVIDE 1729 &1274 BY 91} = 19/14. |

How 3 came? @Gauri. |

Renuka Arvind Chitale said: (Jun 8, 2018) | |

How the 21 comes we write 21% of 24700 so we do 21/100*24700 instead of this we doing 21*24700 how this possible? Please explain. |

@Renuka. Here, 100 and 100 get cancelled. |

Vidhi said: (Dec 29, 2018) | |

From where 3 is coming? Please explain the step. |

Vijaya said: (Dec 8, 2019) | |

3 is divisible in both D numbers 5187 &3822. |

@Gauri. How 3 came? Explain. |
