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 + 2 OCW]
| 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 |
