[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
Spinner capacity to attend=36 breaks in 9 min
The spindles to be allocated per spinner to maintain the same efficiency=?
By unitary rule-
100 spindles have……………..=15 end breakage
So, 1200 spindles have……..=15 x 1200/100 breakage
Total breakage=180
By Unitary rule-
Spinner attend 36 break in…..=9 min
So, will 180 breaks in……..=9 x 180/36
Time taken to attend 180 breaks =45 min
Again by unitary rule-
Spinner attend 1200 spindles in 45 min
i.e
45 min ………………..=1200 spindles
Then, 60 min ………=1200 x 60/45 spindes
Spindles=1600 (Ans)
Spinner attend 1600 spindles in 60 min or 1 hr.
