| Answer | Mark | Comments |
|---|---|---|
| \(13 - 5 \rightarrow 4152\) or \(8 \rightarrow 4152\) | M1 | oe eg \(4152 \div 8\) or 519 seen or 8 parts is 4152 |
| \(\dfrac{x + 4152}{x} = \dfrac{13}{5}\) or \(5x + 20\,760 = 13x\) or \(20\,760 = 8x\) or \(2595 = x\) or (number of men =) 6747 or (number of women =) 2595 or (total number of people =) 12 926 or \(4152 \div 8 \times 7\) or \(519 \times 7\) | M1dep | oe |
