Question

In a certain code language, ‘FIGURE’ is written as ‘DJEVPF’. How will ‘DECODE’ be written as in that language?

The correct answer is

BFAPBF

Let's analyze the coding pattern used to transform 'FIGURE' into 'DJEVPF'. This is a common type of coding-decoding question where each letter in the original word is changed to another letter based on a specific rule.

Understanding the FIGURE to DJEVPF Coding Rule

We compare the letters of the word 'FIGURE' with the letters of the code word 'DJEVPF' based on their positions in the English alphabet.

Original Letter Alphabetical Position Coded Letter Alphabetical Position Difference/Rule
F 6 D 4 4 - 6 = -2
I 9 J 10 10 - 9 = +1
G 7 E 5 5 - 7 = -2
U 21 V 22 22 - 21 = +1
R 18 P 16 16 - 18 = -2
E 5 F 6 6 - 5 = +1

Observing the differences in alphabetical positions, we can see a clear pattern: -2, +1, -2, +1, -2, +1. The rule is to alternately subtract 2 and add 1 to the alphabetical position of each letter to get the coded letter's position.

Applying the Coding Rule to DECODE

Now, let's apply this established coding rule (-2, +1, -2, +1, -2, +1) to the word 'DECODE'.

Original Letter Alphabetical Position Rule Calculation New Position Coded Letter
D 4 -2 4 - 2 = 2 2 B
E 5 +1 5 + 1 = 6 6 F
C 3 -2 3 - 2 = 1 1 A
O 15 +1 15 + 1 = 16 16 P
D 4 -2 4 - 2 = 2 2 B
E 5 +1 5 + 1 = 6 6 F

By applying the -2, +1 sequence rule to each letter of 'DECODE', we get the coded letters B, F, A, P, B, F.

Therefore, 'DECODE' will be written as 'BFAPBF' in this code language.

Matching with Provided Options

Let's compare our result with the given options:

  1. BDDNBD
  2. BFDNBF
  3. BFAPBF
  4. BDANBD

Our calculated coded word 'BFAPBF' matches option 3.

Original Word Coded Word Coding Rule Identified
FIGURE DJEVPF Alternate -2, +1 shift in alphabetical position
DECODE BFAPBF Applied the same alternate -2, +1 shift

Additional Information: Types of Coding-Decoding

Coding and decoding questions test your ability to decipher a hidden pattern or rule. Common types include:

  • Letter Coding: Letters are replaced by other letters based on shifting positions in the alphabet, or other patterns. This question is an example of letter coding.
  • Number Coding: Words are coded using numbers.
  • Symbol Coding: Letters or words are replaced by symbols.
  • Substitution Coding: Words are replaced by other words.

To solve these questions, you need to carefully observe the relationship between the original words and their coded forms, identify the rule, and then apply it to the word you need to code or decode.
