Here, we are asked to solve problem according to the English alphabet. In this case, we have to count both ways. It does mean that we have to count from left to right and from right to left. Let us see the following presentation:

The above presentation makes it clear that the required pairs of letters are 4. (Pairs: DA, EA, ML and LN)

Example: How many pairs of letters are there in the word ‘DREAMLAND’ which have the same number of letters between them as in the English alphabet in the same sequence.

Here we are asked to solve problems according to the alphabetical sequence. It does mean that we have to do counting only from left to right. Let us see the following presentation:

The above presentation makes it clear that the required pair of letters is only one (Pair: LN)
