How to Solve this Coding-Decoding:
Here are some points to keep in minds when we solve these kinds of questions-
* As we all know there is always a concept behind this so we need to find it. When we look at that kind of questions we can see that in all steps all the 4 words start with same alphabet. They all start with- G, T, S and P and there code words also starts with same symbol in each steps- @, %, & and #. So we just have to find which of the first alphabet represent the particular symbol.
* Now we can see that theirs code words end with digits. When we look at that digits are total number of letters for each word.
* Now we can see the middle code word is last letter of that particular word. Now we solve the questions.
Answer 1: B We have to find ‘translate’ code. As we can see that this word is not given in any steps but as we know the idea of that so we can solve it.
Step I: first we will count the letters of that word that is 9, then we put digit 9 at the right end.
Step II: we will put the last letter of that word then it will like- E9
Step III: at the last step ‘t’ is coded for ‘@’(first letter of each word is coded by a specific symbol like here ‘t’ is coded for ‘@’. We can find the first coded symbol by looking at the other given words. Answer will be – @E9
Answer 2: C
We have to find ‘plan’ code-
Now the same steps follow. plan is given in first step. Total count of letters is 4 and last letter is N and ‘p’ is coded as & so Final answer will be- &N4
Answer 3: D
We have given ‘%D4’ and we have to find it’s word. So we can say that the number of letters will be 4 and last digit will be D and ‘%’ is represent to G. so in 3rd step we can find this word, final answer will be –Good
Example (4-8): Consider the following statements and the questions that follow. We will analyse this problem in detail after that.
In a certain code language
“login gradeup and scroll” is written as “&3d @6l *5n %7p”
“scroll for sbi exam” is written as “@6l @3i $3r #4m”
“study exam related notes” is written as “#4m @5y !7d =5s”
“read notes get job” is written as “+3b !4d =5s %3t”
4. Which of the following code is for gradeup?
A. @6l
B. &3d
C. %7p
D. *5n
E. None of these
5. According to the above information, code !7d is used for?
A. study
B. exam
C. related
D. notes
E. read
6. What will be the code for “exam gradeup sbi job”?
A. +3b #4m %7p =5s
B. %3t @6l @5y !7d
C. %7p +3b #4m @3i
D. !4d $3r @6l &3d
E. None of these
7. According to the coding, what will be the code for banking?
A. @7g
B. &7h
C. $7t
D. one of these
E. can’t say
8. What will be the code for probationary?
A. $12y
B. %11n
C. ^12y
D. *13t
E. #12p
Let’s analyse the above information in detail.
Firstly, read the statements and their given codes properly. You can see that there are some words which are common in given statements like scroll, exam, notes and in the codes as well – @6l, #4m, =5s. In codes there are also some special characters which are repeating in different sentences like @ is repeating in all three statements.
From statement 1 and statement 2
“login gradeup and scroll” is written as “&3d @6l *5n %7p”
“scroll for sbi exam” is written as “@6l @3i $3r #4m”
i.e. scroll is common in both statements, so we look for the common code in these two statements, which is @6I.
Similarly, From statement 2 and 3
“scroll for sbi exam” is written as “@6l @3i $3r #4m”
“study exam related notes” is written as “#4m @5y !7d =5s”
From statement 3 and 4
“study exam related notes” is written as “#4m @5y !7d =5s”
“read notes get job” is written as “+3b !4d =5s %3t”
Now scroll = @6l, exam = #4m, notes = =5s
Now, let us understand how the words are coded.
1. Last letter of codes is alphabet and it is same as the last letter of given word.
2. Given number in coding is total letter of words.
So, it is clear that in codes, number represents the total letter of words and the code letter is the last letter of the word
3. But special characters are different for all words. Now our next step is to decode them.
We can see that in statement 2, @ has been used two times in coding and s is also first letter of two words (i.e scroll and sbi). To become sure we can check another words like gradeup and get, both have same % special characters. Similarly, related and read have same (!) special characters.
l g a s f e r n j
* % & @ $ # ! = +
Hence code of word is given as code of first letter, total no. of letters in word and last letter of word.
IMPORTANT: In this question, short clue is total no. of letters in word is given as it is in code.
As per this information,
Answer 4: (C) As we can see in word Gradeup
first letter g = %
total letter = 7
last letter = p
So, code is %7p
Answer 5: (C) ! is code for r, 7 total letters and d is the last letter.
So we can say that related is the word.
Answer 6: (C) Exam = #4m, Gradeup = %7p, sbi = @3i, job = +3b
Hence answer is C.
Answer 7:(E) can’t say. Because we don’t have code for first letter “b” of banking.
All given special character in answer code are @=s, $=f and & = a.
Answer 8:(C) In this question our approach will be options elimination method. As first letter of probationary is ‘p’ and we don’t have any code for p. But in options A, B ,D and E, code of first letter is same as mentioned in above table. So options A,B, D and E are eliminated and our answer will be C.
This was a new pattern question that was introduced in last year’s exams. Let us now have a look at what other sort of pattern changes you can face in Coding-Decoding.
Example (9-12): Consider the following statements and the questions that follow. We will analyse this problem in detail after that.
In a certain code language
“login Gradeup and check” is coded as “$4e %4g #2n @6d”
“reads article study there” is coded as “@6i #4u $4e %4a”
“comment about yours doubt” is coded as “$4u @4o %6m #4u”
“get clear exams enjoy” is coded as “@4e #4a $4j %2e”
9. What is the code for exams?
A. @4e
B. #4a
C. $4j
D. %2e
E. None of these
10.What is the code for study?
A. $4e
B. #4u
C. %4a
D. @6i
E. None of these
11. What is the code for about?
A. %6m
B. $4u
C. @4o
D. #4u
E. None of these
12.If we code “study Gradeup clear exams” as per the above coding method, what will be the code?
A. $6u %4d #4a @4e
B. %4u #4e @6d $4a
C. @4e $6d #6e %4a
D. #6d @4u @4e %4m
E. None of these
Let’s analyse this problem in detail –
Again, read the statements and given codes properly first. In this we can see that all (#$%@) are used in every statement. Clearly, they cannot represent any particular letter because the letters are changing in different statements.
Next if we check number given in coding of first statement – 4,4,2 and 6 are used and letters in word are 5,7,3 and 5. So, numbering given in code is 1 less than number of letters given in word. But we cannot comment about English letter given in code.
#2n = and, @6d = Gradeup, but there is a confusion between $4e and %4g, both login and check are 5 letters word.
From 2nd statement coding we can see that only code @6i has different number (i.e. 6), remaining all codes have number 4. Article is the only word which has 7 letters and we have derived that numbering in coding is 1 less than number of letters in word. So, article = @6i
Now we will try to derive English letter which is given in coding statement.
#2n = and, @6d = Gradeup, @6i = article, hence letter in coding is the middle letter of the word.
Next, Both Gradeup and article are at serial number 2 in statement and both have @ coding.
and is at serial no.3 in statement, so # = 3
Hence we have decoded this coding.
So, we can say that,
numbers in code = total no. of letter in word – 1
Special characters are serial no. of words, % = 1, @ = 2, # = 3 and $ = 4
English letter in code is middle letter of the word.
Important: If you have seen it carefully, you can check that all numbers in codes are even and letters of words in statement is odd. So we can say that there is some addition or subtraction in number of letters of word.
Answer 9 (B): exams is in statement 4 at third place, so for third place code is #, no. of letters in exams is 5, so numerical code is (5-1) = 4 and middle letter of the word is a. So code for it, is #4a.
Answer 10 (B): Study is in statement 3 at third place, so for third place code is #; no. of letters are 5, so numerical code is (5-1) = 4 and middle letter of the word is u. So code for it is #4u.
Answer 11 (C): about is at second place in statement 3, so for second place code is @, no. of ;letters are 5 so numerical code is (5-1) = 4 and middle letter of the word is . so code for it is @4o.
Answer 12 (B): This is a different question, in which you have to code according to above coding method.
study is at first place in statement, so code is %4u.
Gradeup is at second place in statement, so code is @6d.
clear is at third place in statement, so code is #4e.
exams is at fourth place, so code is $4a.
