In a pond there are some flowers with some bees hovering over the flowers. How many flowers and bees are there if both the following statements are true: 1. If each bee lands on a flower, one bee doesn't get a flower. 2. If two bees share each flower there is one flower left out.

The statement "If each bee lands on a flower, one bee doesn't get a flower" is self-contradictory. If each bee lands on a flower then each bees has got a flower.
Also, if two bees share each flower, then each flower has 2 bees on it, and none is left out.

To paraphrase my friend Bill, whether it's contradictory depends on what get gets you and on what left out leaves you out of.
But yeah, @oceanvibe probably means b=f+1 and f=b/2+1

Would it be better to word it thus ?
1. If one bee lands on a flower, there'll be a bee which won't get a flower.
2. If two bees share a flower there is one flower left out.
Which I believe yields 4 bees and 3 flowers.
