• RELATIVE DISTANCE BETWEEN PAIRS OF LETTERS

    In this type of questions, you are required to find out such pairs of letters in the given word which have as many letters between them in the word as in the alphabet.

    If the word is a small one, we can just do the exercise mentally and find out the respective pairs.

    In the word ‘arc’, the letters ‘a’ and ‘c’ are separated by one letter ‘r’ only; and in the English alphabet both these letters ‘a’ and ‘c’ are also separated by one letter ‘b’. From it, we conclude that there is ‘one’ such pair in the word arc, which has as much distance between them as in the English alphabet.

    But, if the word has many letters in it, in such a case, we should note down their place values, because counting is easier than moving between the letters of the English alphabet.

    In the word ‘SUPERSONIC’, there are ten letters, and their place values are as under:

    So, there are 5 pair of letters.

    Now consider the more examples:
