6. Gerallt is planning to go to the Maldives.
His local exchange shop:
- sells 20 Maldivian rufiyaa (MVR) for £1
- takes all possible British notes and coins
- sells MVR notes, but only has 500 MVR and 1000 MVR notes available.
Gerallt has £360 to buy Maldivian rufiyaa (MVR).
Calculate:
- the maximum number of Maldivian rufiyaa (MVR) that Gerallt can buy
- how much this will cost him.
You must show all your working. [5]
Maximum number of Maldivian rufiyaa (MVR) is ……………
The cost is £ ……………
| Scheme | Marks | Comments |
|---|---|---|
| (Change to MVR) 360 × 20 | M1 | |
| 7200 (MVR) | A1 | If not stated, may be implied by 7000 (MVR) |
| (Only 500 and 1000 notes, so can buy) 7000 (MVR) | A1 | FT provided M1 previously awarded |
| (Cost to Gerallt for 7000 MVR is) 7000 ÷ 20 OR 360 – (7200 – 7000) ÷ 20 | M1 | FT ‘multiple of 500 MVR’ provided > 500 |
| (£) 350 | A1 | Depends only on previous M1 awarded If final M0 A0, award SC1 for (£)10 from 200 ÷ 20 |
Alternative method
| Scheme | Marks | Comments |

Considers unambiguously 14 multiples of £25 or 7 multiples of £50 or equivalent, e.g.
| M2 | M1 for any one of the following:
|
| (Considers nearest multiple of £25 < £360) (£)350 | A1 | |
| (Buys) 350 × 20 or 7× 1000 or 14 × 500 or equivalent | M1 | FT ‘their 350’ provided < 360 and it is a multiple of 25 |
| 7000 (MVR) | A1 |
