Corrected by Westie's Workshop
- The board's mark scheme printed “300 ÷ 3”. Changed to “81 ÷ 3” because 81p ÷ 3 gives 27p for 100 ml; 300 ÷ 3 does not give 27.
- The board's mark scheme printed “ml per £: 0.004 and 0.003..”. Changed to “400 and 370.3…” because 1000 ml ÷ £2.50 = 400 ml per £ and 300 ml ÷ £0.81 = 370.3… ml per £.
