How much oil comes out of 50 kg mustard? A person filled it in a drum and brought it to the mill, so many liters of oil came out!

A person shared a very funny video on social media. The person wanted to show people how many liters of oil is produced from fifty kilos of mustard. For this, the person did this experiment by purchasing fifty kilos of yellow mustard and fifty kilos of black mustard. The person reached the mill with both the sacks. After weighing there, he first got the black mustard ground. When this oil was filled in bottles, a total of 18 liters of oil came out. That means, if you grind fifty kilos of black mustard in a mill, you will get eighteen liters of oil from it.
