In a certain code, 'il be pee' means 'roses are blue', 'silk hee' means 'red flowers' and 'pee mit hee ' means 'flowers are vegetables'. How is 'red' written in that code?

silk

1) il be pee means roses are blue

2) silk hee means red flowers

3) pee mit hee means flowers are vegetables

In sentence 2 and 3, "flowers" and "hee" is common. Thus, we can say hee stands for flowers.

Therefore, in sentence only "silk" and "red" is left. Thus, we can conclude that "silk' is the code of "red".
