How many liters of water do you need to add to 12 liters of vinegar essence with 80% vinegar to make table vinegar with 94% water

Given:

vinegar essence 80% – 12 l.

vinegar with a water content of 94%

water -? l.

Let’s take for x – the volume of water. We get the proportion:

12 – 100%

x – 80%

x = 12 * 80: 100 = 9.6 (l.) – vinegar in essence;

12 – 9.6 = 2.4 (l.) – water in essence.

Let’s take for x – the volume of water that should be. We get the proportion:

94% – x

6% – 9.6

x = 94 * 9.6: 6 = 150.4 (l) – there should be water;

150.4 – 2.4 = 148 (l) – add water.

Answer: 148 liters of water must be added to 12 liters of vinegar essence with 80% vinegar content to prepare table vinegar with 94% water content.
