Is Henry correct?
You must show how you get your answer. (4)
| Answer | Mark | Mark scheme |
|---|---|---|
| No with fully correct figures | M1 | for \((360 - 60) \div 2\ (= 150)\) or \(\dfrac{60}{360} \times 480\ (= 80)\) oe |
| M1 | (dep) for method to find required number of students in School A eg \(\dfrac{\text{``}150\text{''}}{360} \times 480\ (= 200)\) or \((480 - \text{``}80\text{''}) \div 2\ (= 200)\) | |
| M1 | for method to find required number of students in School B, eg \(\dfrac{\text{``}90\text{''}}{360} \times 760\ (= 190)\) or \(760 \div 4\ (= 190)\) | |
| C1 | for No with correct figures Acceptable examples No, 200 and 190 He is wrong, School A has 10 more Not acceptable examples Yes .... No, School A had 20 more [incorrect figures] |
Additional guidance
Angle of 150° may be seen on diagram
ft the angle of 90 eg from \(360 - 160 - 110\) calculated incorrectly, or measured incorrectly from the diagram within the range 88 to 92
