| Difficulty | Easy -1.2 This is a straightforward inverse proportion problem requiring students to set up two relationships (A ∝ 1/B and B ∝ 1/C²), combine them to get A ∝ C², then use the given values to find the constant and solve. It's routine algebraic manipulation with no conceptual challenges, making it easier than average but not trivial due to the two-stage relationship. |
| Spec | 1.02r Proportional relationships: and their graphs |
A is inversely proportional to B. B is inversely proportional to the square of C. When A is 2, C is 8. Find C when A is 12. [3]
