Foundation June 2017 Paper 2 Q6
6 There are 495 coins in a bottle.
\(\dfrac{1}{3}\) of the coins are £1 coins.
124 of the coins are 50p coins.
The rest of the coins are 20p coins.
Work out the total value of the 495 coins. (4)
| Answer | Mark | Notes |
|---|---|---|
| 268.20 | P1 | for a process to work out the value of the £1 coins, eg. \(495 \div 3\ (= 165)\) or \(495 \times 0.33\ldots\) or of the 50p coins, eg. \(124 \div 2\ (= 62)\) |
| P1 | for process to find the number of 20p coins, eg. \((495 - 124 - (\text{``}165\text{''})\ (= 206)\) | |
| P1 | for complete process to find total value using consistent units., eg. \((\text{``}165\text{''}) + (124 \div 2) + (\text{``}206\text{''} \times 0.2)\) or \(165 + 62 + 41.2\) | |
| A1 | cao (accept 268.2) |
