Paul buys 12 apples and 10 oranges. 12 apples cost £6. The ratio of the cost of one apple: one orange is 2:3. What is the total cost of the apples and oranges?

Using the ratio one apple: one orange is 2:3 it can be found that one orange = (3/2) * one apple. As 12 apples cost £6, one apple cost £6/12 = 50p. Therefore, one orange = (3/2) * 50p = 75p and 10 oranges cost £7.50. The total cost is therefore £7.50 + £6 = £13.50
