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
 
Answer & Explanation Answer: C) tim

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'.
So, 'tok' means 'bad'.
Thus, in the third statements, 'tim' stands for 'they'.

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
 
Answer & Explanation Answer: B) &N4 and @E9

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.

Answer will be - @E9
