12 Work out \(\quad 65\%\ \text{ of }\ 300\) [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| \(300 \div 10\) or 30 | M1 | oe |
| their \(30 \times 6.5\) or their \(30 \times 6 +\) their \(30 \div 2\) or \(300 -\) their \(30 \times 3.5\) or \(300 - (\)their \(30 \times 3 +\) their \(30 \div 2)\) | M1dep | oe |
| 195 | A1 | SC2 105 |
| Alternative method 2 | ||
| \(300 \div 100\) or 3 | M1 | oe |
| their \(3 \times 65\) or \(300 -\) their \(3 \times 35\) | M1dep | oe |
| 195 | A1 | SC2 105 |
| Alternative method 3 | ||
| Correct method to work out any multiple of 5% of 300 up to 95% | M1 | eg \(50\% = 300 \div 2\) |
| Fully correct build-up method to work out 65% of 300 | M1dep | eg \(300 \div 2 + 3 \times 300 \div 20\) or \(150 + 3 \times 15\) (no errors seen) |
| 195 | A1 | SC2 105 |
| Alternative method 4 | ||
| \(65 \div 100\) or 0.65 or \(65 \times 300\) or 19 500 | M1 | |
| \(300 \times \dfrac{65}{100}\) or \(300 \times\) their 0.65 or their \(19\,500 \div 100\) | M1dep | oe |
| 195 | A1 | SC2 105 |
Additional guidance
| In Alt 3, either a correct method or a correct value must be seen for the first M1 Note that \(300 \times 50\%\) is not allowed as a correct method | |
| If Alt 3 is to be used, the percentage that is attempted must be stated eg \(20\% = 300 \div 5\) | |
| Do not ignore further working for the A mark eg \(300 - 195\) | M1M1A0 |
