| (A) | 125 |
| (B) | 100 |
| (C) | 25 |
| (D) | 12.5 |
[Show Answer]
Option A is correct.
Given in the question-
Winding machine speed=800 m/min
Yarn weight to be wind=4 kg
=4000 gm
Yarn tex=40 tex
Time taken for winding(min)=?
By unitary rule-
1000 m length have=40 gm weight
i.e.
40 gm weight has=1000 meter length
1 gm ………………….=1000/40
Then, 4000 gm has…………=1000 x 4000/40
Total length to be wind=100000 meter
Time taken for winding(min)=Total length to be wind/Winding machine speed
Time taken for winding(min)=100000/800
Time taken for winding(min)=125 (Ans)
