Fruits

For the price of one pineapple, I will buy two oranges. For the price of three oranges, I will buy four apples. I will buy six bananas for the price of three apples. What is the price of one banana if I pay 1 euro for one pineapple?

Correct answer:

B =  0.1875 Eur

Step-by-step explanation:

$$\begin{gathered} A=1\text{Eur} \\ 1A=2P \\ P=A/2=1/2=\frac{1}{2}=0.5\text{Eur} \\ 3P=4J \\ J=3/4\cdot P=3/4\cdot 0.5=\frac{3}{8}=0.375\text{Eur} \\ 3J=6B \\ B=3/6\cdot J=3/6\cdot 0.375=\frac{3}{16}\text{Eur}=0.1875\text{Eur} \end{gathered}$$
