The table given below shows the amount, in grams, of carbohydrate, protein, fat and all other nutrients, per $100$ grams of nutrients in seven foodgrains. The first column shows the foodgrain category and the second column its codename. The table has some missing values.
The following additional facts are known.
- Both the pseudo-cereals had higher amounts of carbohydrate as well as higher amounts of protein than any millet.
- Both the cereals had higher amounts of carbohydrate than any pseudo-cereal.
- All the missing values of carbohydrate amounts (in grams) for all the foodgrains are nonzero multiples of $5$.
- All the missing values of protein, fat and other nutrients amounts (in grams) for all the foodgrains are non-zero multiples of $4$.
- $\text{P1}$ contained double the amount of protein that $\text{M3}$ contains.
What is the median of the number of grams of protein in $100$ grams of nutrients among these food grains?
