| Scheme | Marks | Comments |
|---|---|---|
| 1440 (g of porridge oats) 750 (g of butter) 600 (g of brown sugar) 12 (table spoons of syrup) | B2 | B1 for at least two values correct |
| Scheme | Marks | Comments |
|---|---|---|
| 1.75 kg = 1750 g or 125 g = 0.125 kg | B1 | May be implied in working |
| 1750 ÷ 125 or 1.75(0) ÷ 0.125 | M1 | Allow M1 for 1.75 ÷ 125 or similar from incorrect unit conversion e.g. 17.5 ÷ 125 |
| = 14 (batches of 12 flapjacks) | A1 | CAO |

| A convincing explanation eg. ‘3 more flapjacks, 3 is 25% of 12’ ‘25% of 12 is 3 and 3 more flapjacks are needed to make 15’ ‘3 out of 12 is 25%’ ‘15 is 125% of 12’ | E1 | Do not accept 12 + 3 without further explanation. Allow ‘25% is 3 (flapjacks)’ ‘12/4 = 3’ |
