A kiln holds 2 tonnes of ware and 1.5 tonnes of furniture. What proportion of the heated mass is furniture?

  • A.about 33 per cent
  • B.about 57 per cent
  • C.about 43 per cent
  • D.about 75 per cent

Answer: C

One and a half tonnes out of a total of 3.5 is about 43 per cent. Proportions of this order are why lightweight furniture is worth its considerably higher cost per piece. Furniture cost is set against fuel saved over many firings.
