Scrabble

A popular word game uses one hundred tiles, each of which is marked with a letter or a blank. The distribution of the tiles is shown above, with each letter paired with the number of tiles marked with that letter. Notice that there are two blank tiles. 

If the tiles marked with an "E" are removed, and the rest are placed in a box, then what is the ratio of consonant tiles to vowel tiles in the box?

Note: for purposes of this problem, "Y" is considered a consonant.

Possible Answers:

Correct answer:

Explanation:

Out of the 100 tiles, there are nine "A" tiles, twelve "E" tiles, nine "I" tiles, eight "O" tiles, and four "U" tiles.

If the "E" tiles are removed, there will be 

 vowel tiles.

The number of consonant tiles can most easily be found by adding the number of vowel tiles and blanks:  

.

The rest of the tiles are consonant tiles; subtract from 100 to get

 of them.

Therefore, the ratio of consonant tiles to vowel tiles in the box after removing the "E's" is

 - that is, a 28 to 15 ratio.
