Understanding Letter Coding Analogies

This question presents a letter coding analogy where a word is related to a number based on a specific pattern. We need to identify the pattern in the first pair (RAT : 18120) and then apply the same pattern to the second term (GOD) to find the missing number.

In such analogy problems, the relationship between the first pair of terms (RAT and 18120) provides the rule that must be used to find the missing term for the second term (GOD).

Analyzing the First Pair: RAT : 18120 Coding Pattern

Let's examine the word RAT and consider the alphabetical position of each letter in the standard English alphabet sequence, where A=1, B=2, C=3, and so on up to Z=26.

Now, let's compare these positions with the number 18120 given in the analogy. It appears that the number 18120 is formed by combining or concatenating the alphabetical positions of the letters R, A, and T in their respective order.

• The alphabetical position of R is $18$.
• The alphabetical position of A is $1$.
• The alphabetical position of T is $20$.

If we place these numbers next to each other in the sequence 18, 1, 20, we get the number 18120. Thus, the coding pattern is to take the alphabetical position of each letter and concatenate them.

Pattern identified: Concatenate the alphabetical position of each letter in the word.

Applying the Coding Pattern to GOD

Now, we will apply the same coding pattern to the word GOD to find the corresponding number. First, we find the alphabetical position of each letter in GOD.

Using the concatenation pattern identified earlier, we combine the alphabetical positions of the letters G, O, and D in their respective order:

• The alphabetical position of G is $7$.
• The alphabetical position of O is $15$.
• The alphabetical position of D is $4$.

Concatenating these positions gives $7$ followed by $15$ followed by $4$. This forms the number $7154$.

Determining the Missing Term in the Analogy

Following the established pattern, the number related to the word GOD is 7154.

Verifying with the Given Options

Let's check if the number we derived, 7154, is present among the given options:

1. 7174
2. 7164
3. 7154
4. 7144

Our calculated number, 7154, perfectly matches option 3.

Conclusion on the Letter Coding Solution

The missing term in the analogy RAT : 18120 :: GOD : ______ is 7154. This is determined by identifying that the pattern involves concatenating the alphabetical positions of the letters in the first word (RAT) to form the corresponding number (18120) and applying the same rule to the second word (GOD).

Additional Information on Analogies and Coding Reasoning

Analogies and coding/decoding questions are fundamental parts of logical reasoning tests aimed at assessing a candidate's ability to identify patterns and apply rules consistently. Analogies can be based on various relationships, such as synonyms, antonyms, part-whole, cause-effect, or in coding, specific transformation rules based on letters or numbers.

Letter coding problems specifically often use the alphabetical position of letters, either directly, in reverse order (Z=1, Y=2, etc.), or based on summing/manipulating these positions. Identifying the exact pattern quickly is key to solving these problems efficiently.

Practice with different types of coding and analogy questions helps in recognizing common patterns and developing problem-solving speed and accuracy.
