Foundation November 2019 Paper 1 Q8
8 Prasha has five blocks of wood.
The total weight of all five blocks of wood is 3 kilograms.
4 of the blocks of wood each have a weight of 650 grams.
Work out the weight, in grams, of the other block of wood. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 400 | P1 | for finding the total weight of 4 blocks, eg \(650 \times 4\ (= 2600)\) or \(0.65 \times 4\ (= 2.6)\) or for using 1 kg = 1000g eg \(650 \div 1000\ (= 0.65)\) or \(3 \times 1000\ (= 3000)\) |
| P1 | for subtraction, eg. \(3 \times 1000 - \text{``}2600\text{''}\) or \(3 - \text{``}2.6\text{''}\ (= 0.4)\) | |
| A1 | cao | |
| SC B1 for 2350 |
Additional guidance
Writing 1 kg as 1000g is insufficient without it being used in a calculation
