| Scheme | Marks | Comments |
|---|---|---|
| (65 + 14 + 9) × 27 ÷ 9 (=88 × 3) | M1 | |
| 264 (kg) | A1 | |
| Conclusion that it is not possible as 264 > 250, e.g. ‘No as 264kg is greater than ¼ tonne’ | E1 | FT provided M1 awarded for an appropriate conclusion. Do not accept ¼ tonne as any amount other than correctly giving 250 kg, however it is not essential to state this conversion. |
