| Scheme | Marks | Comments |
|---|---|---|
| Sight of 0·3 x 20 or equivalent | M1 | Award M1 only for 3/10 = 6/20 without a final answer of 6. Allow 3/10 of 20 for M1. |
| 6 | A1 | If candidates calculate the number of apples, bananas and lemons, they must clearly indicate numbers of apples = 6. Allow 6 out of 20 for M1 A1 |
