27 A shop sells packs of black pens, packs of red pens and packs of green pens.
There are
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday,
A total of 212 pens were sold.
Work out the number of green pens sold. (4)
| Answer | Mark | Mark scheme |
|---|---|---|
| 96 | P1 | for process to find the ratio of the number of pens of each colour sold, eg \(2 \times 7 : 5 \times 3 : 6 \times 4\ (= 14 : 15 : 24)\) |
| P1 | for process to find the proportion of green pens sold, eg \(\dfrac{212}{\text{``}14\text{''} + \text{``}15\text{''} + \text{``}24\text{''}}\) or \(\dfrac{\text{``}24\text{''}}{\text{``}14\text{''} + \text{``}15\text{''} + \text{``}24\text{''}}\) | |
| P1 | for a complete process to find the number of green pens sold, eg \(\dfrac{212}{\text{``}14\text{''} + \text{``}15\text{''} + \text{``}24\text{''}} \times \text{``}24\text{''}\) or \(\dfrac{\text{``}24\text{''}}{\text{``}14\text{''} + \text{``}15\text{''} + \text{``}24\text{''}} \times 212\) | |

Additional guidance
For the first P1: Does not have to be seen as a ratio but all three needed
For the third P1: P3 can be implied by the values 56, 60 and 96
