Foundation January 2023 Paper 2R Q5
5 Pat has 4 parcels A, B, C and D
The weight of parcel A is 400 grams.
The weight of parcel B is 350 grams more than the weight of parcel A
The weight of parcel C is twice the weight of parcel A
The total weight of the 4 parcels is 2.5 kilograms.
Work out the weight, in grams, of parcel D
(4)
| Scheme | Marks |
|---|---|
| eg 2.5 kg = 2500 g or 400 g = 0.4 kg or 350 g = 0.35 kg | B1 |
| eg 400 + 350 (= 750) or 0.4 + 0.35 (= 0.75) or 400 × 2 (= 800) or 0.4 × 2 (= 0.8) | M1 |
| eg 2500 – (400 + “750” + “800”) or 2.5 – (0.4 + “0.75” + “0.8”) (= 0.55) | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: 550 | A1 |
| (4) | |
| (4 marks) |
