Assertion (A): A low liquor ratio machine uses less water and energy per kilogram of goods.
Reason (R): There is simply less liquor to fill, to heat and to discharge.

  • 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 arithmetic: halving the ratio halves the water and roughly halves the heating load, which is why machine makers have pushed ratios steadily down. Chemical costs fall in proportion as well.
