## 3. | IGCSE Extended |

In January, a supermarket sold 12 624 boxes of breakfast cereal.

(a) The cost of a box of cereal was £2.15 . Calculate the amount received from the sale of the 12 624 boxes. Give your answer correct to the nearest hundred pounds.

(b) The number of boxes sold in February was 13% more than the number sold in January. Calculate the number of boxes sold in February.

(c) There were 3 different types of cereal. The number of boxes sold of each type every month was in the ratio Riceflakes : Cornflakes : Branflakes = 4 : 5 : 3. The total number of boxes sold was 12 624. Calculate the number of boxes of Branflakes sold.

(d) How may more boxes of Cornflakes than Riceflakes were sold in February?

(e) \(\frac{5}{6}\) of the 12 624 bottles sold in January are included in a special promotion. Calculate the number of boxes that are included in that promotion.

## 4. | GCSE Higher |

The ratio a : b is equivalent to the ratio 7 : 3 and 8b = 5c

Find the ratio a : c in its simplest form.

## 5. | GCSE Higher |

The points A, B C and D lie in order on a straight line.

$$AB:BD = 1:4$$ $$AC:CD = 9:11$$Using the information above calculate the three part ratio:

$$AB:BC:CD$$If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.
