Understanding Code Language and Positional Values

This question asks us to decipher a code language where words are converted into numbers. We are given two examples to help us understand the pattern: 'GOP' coded as '38' and 'HVN' coded as '44'. We need to find the code for 'PNG' using the same logic.

Analyzing the Given Codes: GOP and HVN

Let's look at the letters in the given words and their positions in the English alphabet. We can assign a numerical value to each letter based on its position (A=1, B=2, ..., Z=26).

• For 'GOP':
• G is the 7th letter.
• O is the 15th letter.
• P is the 16th letter.

Let's try adding these positional values together:

G(7) + O(15) + P(16) = 7 + 15 + 16 = 38

This sum matches the given code '38' for 'GOP'.

Now let's check the second example, 'HVN', using the same logic:

• For 'HVN':
• H is the 8th letter.
• V is the 22nd letter.
• N is the 14th letter.

Adding these positional values:

H(8) + V(22) + N(14) = 8 + 22 + 14 = 44

This sum matches the given code '44' for 'HVN'.

Based on these two examples, the pattern or logic used in this code language is the sum of the alphabetical positional values of the letters in the word.

Coding 'PNG' Using the Identified Pattern

Now we apply the same rule to find the code for 'PNG'. We find the alphabetical positional value for each letter in 'PNG'.

• P is the 16th letter.
• N is the 14th letter.
• G is the 7th letter.

Now, we sum these positional values:

P(16) + N(14) + G(7) = 16 + 14 + 7 = 37

Therefore, the code for 'PNG' in this language is 37.

Summary of Calculations

The calculated code for 'PNG' is 37.

Conclusion

The code for 'PNG' is 37.

Code Language Revision

Coding and decoding questions often involve patterns based on:

• Alphabetical positional values (forward or reverse).
• Adding, subtracting, multiplying, or dividing these values.
• Adding or subtracting a constant number.
• Patterns related to vowels or consonants.
• Letter shifting (like in Caesar cipher).
• Mixing or reversing letters.

Additional Information on Coding Decoding

Coding-decoding is a common topic in reasoning ability tests. It checks your ability to identify patterns and apply them to new inputs. Practice with different types of coding (letter coding, number coding, symbol coding) is essential. Always look for the simplest pattern first, like positional values or basic arithmetic operations.
