Men illiterate 40% = 60% literate Children= 85% literate 2:3 ratio 2*100:3*100 200:300 ==200+300=500 60% of 200: 85% of 300 120:255= 120+255=375 Now 375/500==75% |

Why you are subtracting 40% from 100 but not 85%. Will you clear it? |

We Have to find literate percent. For men it was given illiterate percent so we are subtracting from 100, but in case of children literate percents given so no need 2 subtract. |

Why did you multiply 75x/20 with 100/5x? Why did you take 5x? |

Let A for adults and C for children. A : C :: 2 : 3. i.e. A : C = 40 : 60 (from 100 people). So iliterate adult 40% i.e. 40% of 40 people = 16 people (out of 100). So iliterate childs are 15% i.e. 15% of 60 people = 9 people (out of 100). So total iliterate people are 16 + 9 = 25 (from 100). Then literate people 100 - 25 = 75% (Percentage is because we take out of 100). |

@Khadyoth. We have divided the literate population fraction by the total population, i.e, 5x(2x+3x). And multiplied it with 100 to get the percentage. ((75x/20 ÷ 5x) * 100). |

Can't understand please anyone makes it clear. |

Adult : Children. 2x=3x Literate=2 x (60%) + 3x(85%), =120x+255x, =375x. %= 375/500 = 75%. |

100 - 85 = 15 % 100 - 40 = 60 % 15% + 60% = 75 %. Ans: 75%. |

Where from 1/ 5x came? Explain. |

Washington said: (Jan 22, 2019) | |

How did you get that 1/5x? please explain. |

The ratio of adults to children (total) = 2:3. So, adding these ratios up, we can conclude that out of 5 people, 2 of them are adults and 3 of them are children. So, adults = 2/5, children = 3/5. They have taken 1/5 as common, this is how 1/5 comes. hope it helps. |
