How many pairs of letters are there in the word 'LANGUISH' which have the same letters between them in the word as in the alphabet?
We need to find pairs of letters in the word 'LANGUISH' where the number of letters between them in the word is the same as the number of letters between them in the alphabet.
- The word 'LANGUISH' consists of the following letters: L, A, N, G, U, I, S, H. Now, let's check the pairs:
- L and A: There are 11 letters between them in the alphabet (L -> A), but in the word, there are none. Thus, this is not a valid pair.
- L and N: There is 1 letter (A) between them in the alphabet, and in the word, there is exactly one letter between them. This is a valid pair.
- A and G: There are 5 letters (B, C, D, E, F) between them in the alphabet, but in the word, there are none. This is not a valid pair.
Thus, we find three valid pairs. The correct answer is three.
