Solving Coding Decoding Problems

This question asks us to decode a word based on a pattern observed in another coded word. This type of problem is common in logic reasoning and coding-decoding sections of exams. We need to find the rule or pattern applied to the word 'LOGISTIC' to get 'IGOLCITS' and then apply the same rule to 'ATTITUDE'.

Analyzing the Coding Pattern: LOGISTIC to IGOLCITS

Let's look at the letters in the original word 'LOGISTIC' and the coded word 'IGOLCITS'. Both words have the same letters, which suggests the coding is a rearrangement or permutation of the letters.

Let's assign positions to the letters in 'LOGISTIC':

Now, let's look at the coded word 'IGOLCITS' and try to identify where each letter came from in 'LOGISTIC'.

Let's map the letters in the coded word back to their original positions in 'LOGISTIC'. Note that 'I' appears twice in 'LOGISTIC' at positions 4 and 7.

• The first letter 'I' in 'IGOLCITS' (position 1) is the 'I' from 'LOGISTIC' (either position 4 or 7).
• The second letter 'G' in 'IGOLCITS' (position 2) is the 'G' from 'LOGISTIC' (position 3).
• The third letter 'O' in 'IGOLCITS' (position 3) is the 'O' from 'LOGISTIC' (position 2).
• The fourth letter 'L' in 'IGOLCITS' (position 4) is the 'L' from 'LOGISTIC' (position 1).
• The fifth letter 'C' in 'IGOLCITS' (position 5) is the 'C' from 'LOGISTIC' (position 8).
• The sixth letter 'I' in 'IGOLCITS' (position 6) is the 'I' from 'LOGISTIC' (the other 'I', either position 4 or 7).
• The seventh letter 'T' in 'IGOLCITS' (position 7) is the 'T' from 'LOGISTIC' (position 6).
• The eighth letter 'S' in 'IGOLCITS' (position 8) is the 'S' from 'LOGISTIC' (position 5).

Assuming the 'I' at position 4 in 'LOGISTIC' goes to position 1 in 'IGOLCITS' and the 'I' at position 7 goes to position 6, the pattern of original positions forming the coded word is:

Original Positions: 4, 3, 2, 1, 8, 7, 6, 5

Let's verify this pattern:

• Position 4 of LOGISTIC is I
• Position 3 of LOGISTIC is G
• Position 2 of LOGISTIC is O
• Position 1 of LOGISTIC is L
• Position 8 of LOGISTIC is C
• Position 7 of LOGISTIC is I
• Position 6 of LOGISTIC is T
• Position 5 of LOGISTIC is S

Combining these letters in this order gives "IGOLCITS", which matches the given coded word. The pattern is indeed the rearrangement of letters based on their original positions: 4th, 3rd, 2nd, 1st, 8th, 7th, 6th, and 5th letters.

Applying the Pattern to ATTITUDE

Now we apply the same positional rearrangement pattern to the word 'ATTITUDE'. First, let's number the positions of the letters in 'ATTITUDE':

We need to take the letters from these positions in the sequence: 4, 3, 2, 1, 8, 7, 6, 5.

• Letter at Position 4 is I
• Letter at Position 3 is T
• Letter at Position 2 is T
• Letter at Position 1 is A
• Letter at Position 8 is E
• Letter at Position 7 is D
• Letter at Position 6 is U
• Letter at Position 5 is T

Putting these letters together in the order 4, 3, 2, 1, 8, 7, 6, 5, we get:

I T T A E D U T

Comparing with Options

Let's check our result against the given options:

1. ITTAEDUT
2. TTIAUTDE
3. TAITUTED
4. ITTAUTDE

Our derived code "ITTAEDUT" matches Option 1.

Conclusion

By analyzing the coding pattern used to transform 'LOGISTIC' into 'IGOLCITS', we found it's a positional rearrangement. Applying this pattern to 'ATTITUDE' gives us the coded word 'ITTAEDUT'.

Additional Information: Types of Coding Decoding

Coding-decoding is a vital part of logical reasoning tests. Questions involve finding the rule that links a coded word/number/symbol to its original form and applying it to a new input. Common types include:

• Letter Coding: Letters are replaced with other letters based on a pattern (e.g., shifting positions in the alphabet, reversing order, specific substitutes). The pattern could be simple shifting (+1, -2), skipping letters, or a mixed series.
• Number Coding: Words are coded into numbers. The pattern might be based on the alphabetical position of letters, the number of letters, or specific arithmetic operations on these values.
• Symbol Coding: Letters or words are coded using symbols.
• Substitution Coding: Objects are replaced with other objects (e.g., 'red is called blue', 'blue is called green').
• Mixed Letter and Number Coding: Both letters and numbers are used in the code.
• Positional Coding (like this question): The letters of the original word are rearranged based on their positions following a specific rule. This rule could be reversing the word, splitting the word and reversing parts, or a custom positional swap like the example above.

To solve coding-decoding problems, practice is key. Look for patterns in letter substitution, letter position, number relationships, and common sequences.
