Assertion (A): Right first time is used as the headline measure of dyehouse performance.
Reason (R): A failed batch consumes machine time, water, energy and chemicals a second time.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Both are true and the reason gives the economics: a redye is the most expensive thing a dyehouse does, since it doubles the cost of a batch and delays every batch behind it in the queue. The definition is deliberately strict. Anything short of a clean pass is a failure. Machine time is the largest part of the cost.
