In a certain code language, ‘TIDE’ is coded as ‘9457’ and ‘DENT’ is coded as ‘7593’. What is the code for ‘N’ in that language?

Question

Accepted Answer

Let's analyze the given codes:

- TIDE is coded as 9457
  Letters: T I D E
  Codes: 9 4 5 7

- DENT is coded as 7593
  Letters: D E N T
  Codes: 7 5 9 3

From the first word:
- T -> 9
- I -> 4
- D -> 5
- E -> 7

From the second word:
- D -> 7
- E -> 5
- N -> 9
- T -> 3

Notice that the same letter has different codes in the two words, so the position of the letter in the word corresponds to the digit in the code.

Check the position of N in DENT:
- D (1st letter) -> 7
- E (2nd letter) -> 5
- N (3rd letter) -> 9
- T (4th letter) -> 3

Therefore, the code for N is 9.

But the options show 9 as option 4, however, the question asks for the code for N.

Wait, there is a discrepancy because in TIDE, D is 5, but in DENT, D is 7. So the code is not consistent by letter but by position.

Let's check the position-wise coding:

In TIDE (positions 1 to 4): 9 4 5 7
In DENT (positions 1 to 4): 7 5 9 3

So position 1 letter codes: T=9, D=7
Position 2 letter codes: I=4, E=5
Position 3 letter codes: D=5, N=9
Position 4 letter codes: E=7, T=3

So the code depends on the letter and position.

Since N is the 3rd letter in DENT, and the 3rd digit in code is 9, the code for N is 9.

Hence, the correct answer is 9.
