Answers
The pairs of letters in the word nursing are - 2. Three
- Taking the first letter as N, thus NU will have six letters between them. Here as they do not have any letter, hence it can's be a possible pair.
- If we go to NR, then again NR will have only a letter between them which is not applicable in english alphabets.
- Proceeding in same manner, it could be found that the words fulfilling the given requirement are US, RS and RN.
- Therefore, there are only three pairs of words between the word Nursing.

The question like this can better be solved using a table to figure out the answer

Step 3 : find the number of letters in between the letters in first column and second column of word NURSING.
eg: in first column,the letters are N and U.As there is no letter between N and U in word NURSING,value in column 3 is 0.
fill all the columns
Step 4 : find the number of letters in between the letters in first column and second column from Alphabet series.(ABCDEFGHIJKLMNOPQRSTUVWXYZ)
eg: in first column,the letters are N and U.As there is 6 letter(OPQRST) between N and U in alphabet series,value in column 3 is 6.
