6*2=12, 6*3=18,6*5=30 in the same way 8*2,8*3,8*5. So last one 9*5=45,9*2=18,9*3=27 this also be the way of guessing the answer. |

18+12 = 30; 30/5 = 6. also 16+24 = 40;40/5 = 8. So larger number divided by 5 is the answer. So 45/5 = 9 is the answer. |

Check for the no which are below line like 12, 18, 30 divisible by 6, simliarly its 9. |

Option: C Explanation: 12,18,30 = 6(2,3,5). 16,24,40 = 8(2,3,5). 45,18,27 = 9(5,2,3). Hence the HCF of the other numbers is the result. |

12, 8, 30 divisible by 6. 16, 24, 40 divisible by 8. According to that, 45, 18 and 27 are divisible by 9. So answer is 9. |

6*2=12 8*2=16 9*2=18. 6*3=18 8*3=24 9*3=27. 6*5=30 8*5=40 9*5=45. |

12+18=30 & 18-12=6. 24+16=40 & 24-16=8. 18+27=45 & 27-18=9. |

Ramesh said: (Oct 18, 2014) | |

12+18+30 = 60/10 = 6. 16+24+40= 80/10 = 8. 45+18+27 = 91/10 = 9. |

Actually the right method is by dividing 10 to each set. But in my book the answer is 12 can some one explain whether its 12 or 9. |

Vijay Chandel said: (Jul 10, 2015) | |

Answer : 6. 30-12 = 18/3 = 6. 40-16 = 24/3 = 8. 45-27 = 18/3 = 6. |

Keshav said: (Nov 23, 2016) | |

Not understand. Please explain in a simple and clear way. |

Hanshu said: (Jan 26, 2017) | |

6 * 3 = 18. 8 * 3 = 24. 6 * 3 = 18. |

Ajith C R said: (Jul 5, 2017) | |

Simply we can multiply by 5. 6*5=30. 8*5=40. 9*5=45. |

Arvind Kumar said: (Nov 21, 2017) | |

18+12 = 30; 30/5 = 6. Also 16+24 = 40;40/5 = 8. So larger number divided by 5 is the answer. So 45/5 = 9 is the answer. |

6*2=12 6*3=18 6*5=30 8*2=16 8*3=24 8*5=40 18÷2=9 27÷3=9 45÷5=9. Therefore the answer is option (C) 9. |

Varun said: (Jun 5, 2018) | |

Yeah @Niveditha. It's correct I agree with your answer. |

Abilash said: (Aug 13, 2018) | |

How come 10? please explain. |

Kens said: (Aug 15, 2018) | |

What's the standard formula to solve it? Please anyone tell me. |

Anoms said: (Apr 17, 2019) | |

How? Explain. |

R.Santhoshini said: (Sep 19, 2019) | |

12-30 = 18, so smallest number subtraction by 18-12 = 6 16-40 = 24, so smallest number subtraction by 24-16 = 8 45-27 = 18, so smallest number subtraction by 18-27 = 9 Therefore the answer is an option (c) 9. |
