Foundation January 2020 Paper 2R Q10
10 Here are four different numbers written in order of size.
\(3 \qquad 6 \qquad m \qquad n\)
The range of the four numbers is 13
The median of the four numbers is 8.5
Find the value of \(m\) and the value of \(n\).
(2)
| Scheme | Marks |
|---|---|
| \(n - 3 = 13\) oe or \(n = 16\) or \((6 + m) \div 2 = 8.5\) oe or \(m = 11\) | M1 |
| \(n = 16\) & \(m = 11\) | A1 |
| (2) | |
| (2 marks) |
Notes
A1: Both values correct
