Understanding the Letter Arrangement Problem

The question asks us to take the letters of the word "KINGDOM", arrange them in alphabetical order, and then find the number of letters in the standard English alphabet that are between two specific letters in this new arrangement: the fourth letter from the left and the second letter from the right.

Step 1: Arrange the Letters of KINGDOM Alphabetically

First, let's identify the letters in the word KINGDOM:

• K
• I
• N
• G
• D
• O
• M

Now, we arrange these letters in their standard alphabetical order. The English alphabet order is A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

Arranging the letters D, G, I, K, M, N, O alphabetically, we get:

The new letter-cluster formed by arranging the letters of KINGDOM in alphabetical order is D G I K M N O.

Step 2: Identify the Required Letters in the New Cluster

We need to find two specific letters in the new letter-cluster (D G I K M N O):

• The letter which is fourth from the left.
• The letter which is second from the right.

Let's count from the left in D G I K M N O:

$1^{st}$ from left: D

$2^{nd}$ from left: G

$3^{rd}$ from left: I

$4^{th}$ from left: K

So, the fourth letter from the left is K.

Now, let's count from the right in D G I K M N O:

$1^{st}$ from right: O

$2^{nd}$ from right: N

So, the second letter from the right is N.

Step 3: Count Letters Between K and N in the English Alphabet

We need to find how many letters are there in the English alphabetical series between the letter K and the letter N.

Let's look at the segment of the English alphabet around K and N:

... J, K, L, M, N, O ...

The letters that appear strictly between K and N in the standard English alphabet are L and M.

Counting these letters, we find there are two letters (L and M) between K and N.

Conclusion

The number of letters in the English alphabetical series between the letter which is fourth from the left (K) and the one which is second from the right (N) in the new letter-cluster formed by arranging KINGDOM alphabetically is two.

Additional Information: Alphabetical Reasoning

Problems like this test your ability to work with the English alphabet, understand order, and identify positions. They often involve:

• Arranging letters of a word alphabetically or in reverse alphabetical order.
• Finding letters at specific positions from the left or right end.
• Counting letters between two given letters in the standard alphabet sequence.
• Performing operations like skipping letters or replacing letters.

Practicing the standard order of the English alphabet (A to Z) and being comfortable with counting positions from both ends is key to solving such alphabetical reasoning questions efficiently.
