| (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)
