Understanding Coding and Decoding Logic

This question involves a type of coding and decoding where letters of a word are directly substituted by specific symbols or characters based on a given pattern. We are provided with two examples of words coded into symbols:

• APRIL is coded as ÷×βα@
• MARCH is coded as €÷β©∞

Our goal is to find the code for the word PARAM using the same logic.

Step-by-Step Decoding Pattern Analysis

Let's analyse the given codes to identify the symbol assigned to each letter. We can create a mapping based on the two examples provided.

From this mapping, we can see that the symbol for each letter is consistent across the examples where the letter appears. For instance, 'A' is always ÷, and 'R' is always β.

Coding the word PARAM

Now, let's use the established letter-symbol mapping to code the word PARAM. We will take each letter in PARAM and find its corresponding symbol from our mapping table.

• P corresponds to ×
• A corresponds to ÷
• R corresponds to β
• A corresponds to ÷
• M corresponds to €

Putting these symbols together in the order they appear in PARAM (P-A-R-A-M), we get the code:

×÷β÷€

Comparing with Options

Let's compare the derived code ×÷β÷€ with the given options:

• Option 1: ×÷β÷€
• Option 2: ÷×÷€β
• Option 3: β×÷©€
• Option 4: ÷β×÷€

The code we derived for PARAM matches Option 1 exactly.

Additional Information - Types of Coding Decoding

Coding and decoding questions are common in logical reasoning sections of various exams. They test your ability to decipher patterns and rules. Common types include:

• Letter Coding: Letters are replaced by other letters based on a pattern (e.g., shifting positions, opposite letters).
• Number Coding: Words are coded using numbers.
• Symbol Coding: Letters or words are coded using symbols, as seen in this question.
• Mixed Coding: A mix of numbers, letters, and symbols is used.
• Sentence Coding: Entire sentences are coded, and you need to find codes for individual words.

The key to solving these problems is careful observation of the given examples to identify the underlying rule or pattern before applying it to the word that needs to be coded or decoded.
