Five of the numbers are
3 2 7 6 2
The other number is \(x\).
Work out the value of \(x\).
(3)
| Scheme | Marks |
|---|---|
| 6 × 5 (= 30) or 3+2+7+6+2 (=20) or (3+2+7+6+2 +“x”)/6=5 | M1 |
| “30” − “20” | M1 dep |
| 10 | A1 |
| (Total 3 marks) |
Notes
Apart from questions 5b, 8, 15d, 20b, 21b, 23, 24b (where the mark scheme states otherwise) the correct answer, unless clearly obtained by an incorrect method, should be taken to imply correct working.
