Fatimah prepared a container of drink for their guest. She mixed some concentrated orange juice with water to make the drink. From the instruction given on the bottle of concentrated orange juice, every 6 parts of the juice is to mix with 19 parts of water to make the drink. Fatimah used 4 864 m^{3} of water to prepare the drink. What is the total volume of the drink?

Solution:

Every 6 parts of the juice is to mix with 19 parts of water to make the drink

The ratio of orange juice to water to make the drink = 6 : 19

The amount of water used = 4864 m^{3}

From the model

19units = 4864

1 unit = 256 m^{3}

Total volume of the drink = 25 × 256 = 6400 m^{3}
