A precision winder has to wind 4 kg of yarn of 40 tex

###### Question 80 (Textile Engineering & Fibre Science)

If the machine winds at 800 m/min, without any interruption, the time (min) taken for winding would be

(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)
