# Coding and Decoding Questions

Q:

In a certain code language, '3a, 2b, 7c' means 'Truth is Eternal';

'7c, 9a, 8b, 3a' means 'Enmity is not Eternal'  and

'9a, 4d, 2b, 8b' means 'Truth does not perish'.

Which of the following means 'enmity' in that language ?

 A) 3a B) 7c C) 8b D) 9a

Explanation:

Justification:

In the second and third statements, the common code is '9a' and the common word is 'not'.

So, '9a' means 'not'.
In the first and second statements, the common codes are '7c' and '3a' and the common words are 'is' and 'Eternal'.
So, in the second statement, '8b' means 'enmity'.

Q:

(A)  '134' means 'you are well';

(B)  '758' means 'they go home';

(C)  '839' means 'we are home';

Which of the statements can be dispensed with while answering the above question?

 A) A only B) B only C) A or C only D) B or C only

Explanation:

Justification:

We can find the code for 'home' from the second and third statements.

For finding the code for 'they', we need the code for 'go' which cannot be determined from the given data.
Clearly, statement A is not necessary.

Q:

Coding-Decoding

If Pour is wrtten as 4156
Sware is written as 78269
Clear is written as 3@926

Then what is the code for PEARL= ?

 A) 429@6 B) 4962@ C) 4692@ D) 4926@

Explanation:

Pour - 4156 => P = 4,  r = 6

Sware - 78269 => a =  2,  e = 9

Clear - 3@926 => l = @

=> Pearl = 4926@

Q:

If in a code language, COULD is written as BNTKC and MARGIN is written as LZQFHM, how will MOULDING be written in that code ?

 A) CHMFINTK B) LNKTCHMF C) LNTKCHMF D) NITKHCMF

Explanation:

Each letter in the word is moved one step backward to obtain the corresponding letter of the code

Q:

In a certain code language

" given  time  simple  plan " is written as ' @E4  &N4  %N5  #E6 '

" tired  solution  plant  great " is written as ' #N8  @D5  %T5  &T5 '

" sick  point  good  turn " is written as ' #K4  %D4  @N4  &T5 '

" garden  sister  phone  team " is written as ' &E5  #R6  %N6  @M4 '

Which of the following code is for ' plan ' and ' translate ' ?

 A) @E8 and &N5 B) &N4 and @E9 C) @E1 and &N4 D) &N4 and @D7

Explanation:

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

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.

Q:

In a certain code language,

(A) ‘pit dar na’ means ‘you are good’

(B) ‘dar tok pa’ means ‘good and bad’

(C) ‘tim na tok’ means 'they are bad’

In that language, which word stands for 'they' ?

 A) na B) tok C) tim D) pit

Explanation:

Justification:

In the first and third statements, the common word is 'na' and the common word is 'are'.

So, 'na' means 'are'.
In the second and third statements, the common code word is 'tok' and the common word is 'bad'.
Thus, in the third statements, 'tim' stands for 'they'.

Q:

If HAT is coded as 'jcv' then what will GUN be coded as?

 A) iwp B) IKM C) kip D) Klp

Explanation:

Here HAT is coded as jcv

=> Leaving a letter in between i.e, after H leave i write j in small letters

In the same way, A => c, T => v

Similarly for GUN => iwp
