How many pairs of letters are there in the word 'COMPOUND' such that the number of letters between them is the same as in the English alphabet, in both forward and backward directions?

One
Two
Three
Four

Correct answer: Two

Solution

We need pairs whose alphabetical distance equals the number of letters between them in the word. In 'COMPOUND', the valid pairs are C-O and M-P, so there are two such pairs. The condition applies in both directions, meaning the same gap works whether read left-to-right or right-to-left.
