###### Question 78 (Textile Engineering & Fibre Science)

The loss (%) in machine efficiency due to end breakage is

(A) | 7.5 |

(B) | 1.0 |

(C) | 0.75 |

(D) | 0.50 |

**[Show Answer]**

Option c is correct.

Given in the question-

No. of spindes assigned to a spinner=1200

End breakage rate=15 per 100 spindles -hours

The number of standing breaks at any time =9

The loss(%) in machine efficieny due to end breakage=?

By unitary rule-

100 spindles have……………..=15 end breakage

So, 1200 spindles have……..=15 x 1200/100 breakage

Total breakage=180

By formula-

Loss(%) in machine efficiency=Number of standing breaks x 100/Total spindles assigned

Loss(%) in machine efficiency=9 x 100/1200

Loss(%) in machine efficiency=0.75 (Ans)
