How we got the answer? |

How to work to find answer? |

The fineness Modulus (FM) of Coarse aggregate is higher than combined and fine aggregate. The FM of fine aggregates is lowest. And FM of combined aggregate is in between. Here, X = Coarse aggregate = Largest value. Y = Fine aggregate = Lowest value. Z = Combined aggregate = Intermediate value. Compare it with the answer. You will get the required information. |

Z- Combined Aggregate. (Both fine & Coarse), So value should be highest? |

Darshan H A said: (Jun 29, 2016) | |

Question should be percentage of fine aggregate to coarse aggregate not combined aggregate. |

Nayandeep said: (Aug 22, 2016) | |

B and E options are same if we take sign common. |

Faisal said: (Nov 30, 2016) | |

According to me, It is option D. |

Rohit Negi said: (Jul 14, 2017) | |

According to me, the Answer is D. |

Sheela said: (Jul 25, 2017) | |

B is correct. I agree. |

Chetan said: (Aug 25, 2017) | |

No, answer is correct, according to question. @Darshan H A 100%correct. Let FA/CA=m then the ratio of FA with combined aggregate is m/ (m+1). Now solve you get the desired answer. |

Garry said: (Dec 2, 2017) | |

None of the above is correct. Correct is, (X-Z)/(X-Y). |

S.Bhakta said: (Jun 16, 2018) | |

Answer is obviously D. |

Virender Paul said: (Jul 14, 2018) | |

Answer is correct. Because coaser particle will be greater than combined or finer so answer should be coarser-combined/combinef-fine. |

Manohar said: (Nov 20, 2018) | |

pY+X(1-p)=1 * Z. It is p = (X-Z) ÷ (X-Y). |

Vivek Mishra said: (Feb 27, 2019) | |

You are right, thanks @Manohar. |

(CALCULATING RATIO OF FINE AGGREGATE TO COARSE AGGREGATE). Let "x1" is the percentage of fine aggregate to be combined with coarse aggregate. x can be calculated using the formula given below. x = [(F2-F)/(F-F1)] * 100. Where, F1 = Fineness modulus value of the fine aggregate. F2 = Fineness modulus value of coarse aggregate. F = Fineness modulus value of the combined aggregate. After finding the percentage of fine aggregate to be combined with the coarse aggregate by the above formula, their proportion can be calculated. |

Rishabh said: (Sep 26, 2020) | |

It should be p={(X-Z)/(X-Y)}*100%. |

Pratusha Shankar Arepelli said: (Jun 3, 2021) | |

How to calculate it? Please explain in detail. |
