# Three Sentences

Logic Level 3

Barbara, Robert and Michaelle each wrote a sentence on their own copybook that must be completed accurately. The three sentences are the following: $\textrm{Barbara}: \;\boxed{\textrm{ In this sentence there are ... letters. }}$ $\textrm{Robert}: \;\boxed{\textrm{ In this sentence there are ... vowels. }}$ $\textrm{Michaelle}: \;\boxed{\textrm{ In this sentence there are ... consonants. }}$ Each of them tries to insert a number (written in words) such that the sentence is true. Which of them can insert an appropriate number in words?

Details and Assumptions:

Assume we use the English alphabet. A, E, I, O, U are vowels and the remaining letters (including W and Y) are consonants.
