I cannot understand how IBM sales if go up by 50% contribute to increase of 14 to total sales? |

Anoop said: (Oct 25, 2011) | |

Total sales in value in 2005 = US $1,650,000. Since this is all about percentage the value doesn't matter. So we assume the total sales in value in 2005 = US$100(instead of 1650000) In 2005 IBM's contribution was 28% = $28(in cash) IBM got 50% increase in sales ie $14 (14% of 100) In 2005 Apples's contribution was 14% = $14(in cash) Apple got 15% increase in sales ie $ $2.1 (2.1% of 100) The net increase in sales = 14+2.1 =16.1 %ge increase in sales = 16.1*100/100 = 16.1 |

@Anoop. From where did you get 14 and 2.1 ? |

Avani said: (Oct 13, 2014) | |

IBM PC increased by 50% that is (28*150)/100 = 42. So here increase is 42-28 = 14. Apple increased by 15 % that is (14*115)/100 = 16.1. So here increase is 16.1-14 = 2.1. Hence total increase 14+2.1 = 16.1. |

Here 50% of IBM sales is increased okay but why you are taking 50% on 28 instead of 10%? Because 1st chart is of market share, second chart is of sales. |

Reena said: (Jun 7, 2016) | |

Because they have specified it to be in terms of value. |

Shivani said: (Oct 22, 2016) | |

Please explain the method to solve the question. |

Inayat said: (Dec 7, 2016) | |

The answer should be D here "None of these". The chart shows market share in %, all percentages together is 100%. Somehow total share should not exceed more than 100%. All companies together market share should be 100%. In this case, when sale % increases market share is gone to 116.1% which will not be correct. If you want to balance, other companies market share to be reduced to balance to 100%. So the answer can be D. If I'm wrong please explain me in a little better way how the answer is A? |

Can you please explain how did you get 150 and 115? |

Nafeesa said: (Oct 19, 2018) | |

@All. 50% increase means 150 (50+100) and 15% means 115. |

Thanks @Avani. |

Harry said: (Jun 4, 2020) | |

At last step, why did you do multiplication with 100 and divide 100 with 16.1? |

Barac said: (Jan 22, 2021) | |

50% of 28 = 28*(50/100) = 14, 15%of 14=14*(15/100) = 2.1. Therefore total increased = 14+2.1 = 16.1. |
