Coding and Decoding III- Language based Coding Decoding Questions

In the 3rd post on Coding Decoding, we’ll discuss language based Coding Decoding questions that are asked in SSC CGL, IBPS PO and other Bank Exams.

Coding Decoding Questions that are based on language coding can be solved in just a few seconds if you can identify the pattern that runs through the question. And you all know how important coding decoding as a topic is when you are preparing for exams like SSC CGL, IBPS PO and SBI PO because 3-8 questions are always asked from coding decoding. In our previous two blog posts in the series on coding decoding we discussed the various reasoning tricks used in coding decoding and how to solve coding decoding questions. So before we move to language based coding decoding and symbol based coding decoding, you must quickly revise the different kinds of tricks used in coding decoding.
Coding Decoding

Set I – Language based Coding Decoding Problems

Coding Decoding questions from Language coding are asked in exams like SSC CGL and IBPS PO. So it becomes imperative for you to master the reasoning tricks involved in this kind of coding decoding. In such a code, sentences are written in regular English and then coded by a combination of words that are in random order. Usually 3-4 such sentences make up a code. At the end often we have to find the code for an entire sentence, or sometimes for individual words from the sentences.

Problem 1: In a certain code-
coding decoding
(i)                 What is the code for ‘him’?
(ii)               What does ‘bi’ stand for?
(iii)             What is the code for ‘order’?
(iv)              ‘fo ve do’ could be the code for which of the following-
(a)   In right spirits     (b) only in profit     (c) order only him      (d) place in right

Solution 1:
If you notice in this coding decoding question, 4 different sentences are given and 4 different set of codes are given to represent those sentences. Now we need to identify the code for each of the words in the 4 statements. One important thing to note in coding and decoding questions like this is that- Codes in the right hand side are not in the same order as the words in the sentences on the left hand side, because the codes on the right hand side are jumbled. To identify these words we have to find words that occur in 2 or 3 sentences and then spot the code that represents the word.

So let’s start solving this coding decoding question, by identifying one such word that occurs in more than one sentence. The word ‘for’ comes in the 1st, 2nd and 3rd sentence, so the code for ‘for’ also has to be there in all the 3 sentences.
Coding Decoding
On observing we find that ‘ga’ is the common code that occurs in all the three sentences. So in this coding decoding question, we can say-
coding decoding
The next common word that occurs in 1st, 3rd and 4th sentence is ‘order’, so form these three sentences we can identify the code for ‘order’
coding decoding
So now we know the-
coding decoding
Now that no word in common in three statements, we start looking for words that are common in two statements. Following suit, the common word that appears in 1stand 2nd sentence is ‘now’, so form these three sentences we can identify the code for ‘now’-
coding decoding
We now have the code for ‘now’-
coding decoding
After this, there in only one word in the 1st sentence whose code we haven’t identified and hence only one code is there on the right hand side which hasn’t been assigned a word. Coding decoding this we get-
coding decoding
Identifying the common word from the 2nd and 4th sentence, we get the word ‘right’-
coding decoding
Now we have the code for ‘right’-
coding decoding
Now in this coding and decoding question, the only word whose code we haven’t identified in the 2nd sentence is ‘him’ and the only code that doesn’t have a word assigned to it is ‘se’. So,
coding decoding
Similarly, the word left out in the 3rd sentence is ‘place’ and based on the only code left, we conclude-
coding decoding
Now comes the interesting bit, in this coding and decoding question, in the last sentence there are two words left whose code we haven’t decoded.
coding decoding
If you notice, there are two words left-
coding decoding
Since both these words are only in the 4th sentence, we cannot find the codes for them as it could be either of the two codes. So, in coding and decoding questions when this situation arises, we go with the option- cannot be determined.

Now, we can answer coding decoding questions based on this set of codes-
(i)                 The code for ‘him’ is ‘se’
(ii)                ‘bi’ stands for ‘place’
(iii)             The code for ‘order’ is ‘ye’
(iv)              This question is particularly interesting. We know that the code ‘ve’ represents ‘right’ and the code ‘du’ is representative of either ‘only’ or ‘in’. The 3rd code is not present in any of the 4 sentences, which means it is a new word. Using all this information we can get the answer. Based on this we can eliminate option (b) and (c) since they do not have the word right. We need a new word, one that is not there in any of the 4 sentences, to represent the code ‘fu’ and option (a) has a new word ‘spirits’.

Hence, in language based coding decoding question, once you find out the words representing the respective codes, answering questions based on them becomes really simple.

Set II – Symbol based Coding Decoding Problems

In coding decoding questions from this category asked in SSC CGL and IBPS PO, the code for the letters in given in the form of a symbol or number followed by a few conditions. So before you rush to answer the questions based on coding decoding, it is imperative to check the conditions.

Problem 1: In a certain code-
coding decoding
Conditions:
(i)                 If both the first and the last letters are vowels, their codes are to be interchanged.
(ii)               If the first letter is a consonant and the last letter is a vowel, both are to be coded as the code for the vowel
(iii)             If the first  letter is a vowel and the last letter is a consonant, both are to be coded as the code for the consonant
Based on the codes and conditions how will the following words be coded-
1.      AMZGUB
2.      GDWZMI

Solution 1:
Coding and decoding questions like this are asked in SSC CGL, IBPS PO and SBI PO. While solving such questions you must remember that English has 26 letters out of which 5 are vowels.
coding decoding
There remaining 21 letters are called consonants.
1.      Let’s get the code for the first word - AMZGUB
Now the minute you read this word, you should go back to the conditions and see which condition will apply to this word. On reading, we find that the 3rd condition applies to the given word, since the first letter is a vowel and the last letter is a consonant. So based on given condition for coding and decoding, we know that ‘A’ and ‘B’ will both be coded as the consonant ‘B’.
So going to the table of codes given in this question we get-
coding decoding
Hence, the code for the given question is-
coding decoding
2.      Let’s solve the 2nd part of the question – GDWZMI
The first thing you should do now is go back to the conditions for this coding decoding question and see which condition will apply here. On reading we realize that the 2nd condition will hold true here, as the first letter is a consonant and the last letter is a vowel. So applying the given condition, ‘G’ and ‘I’ will be both coded as ‘I’.
Referring to the table of codes, we get-
coding decoding
Hence the code for the given word will be-
coding decoding
So solving coding decoding questions like this is really simple, all you have to do is verify the conditions.

Practice Questions for Coding Decoding

Directions for Questions 1- 5: In each of these questions a group of letters is given followed by four Combinations of number/symbol numbered 1), 2), 3) & 4). Letters are to be coded as per the scheme and conditions given below. You have to find out the serial number of the combination which represents the letter group. The serial number of that combination is your answer. If none of the combinations is correct, your answer is 5), i.e. 'None of these'.

Conditions:
        i.                 
If the first letter is a consonant and the last a vowel, both are to be coded as the code for                        the vowel. 
ii.                  If the first letter is a vowel and the last a consonant, the codes for the two are to be interchanged.
iii.                If both the first and the last letters are consonants, both are to be coded as '§'.
iv.                 If there are more than two vowels in the group of letters, all vowels are to be coded as '£'
