Olympiad Test: Coding-Decoding - 3 - Class 6 MCQ

In the given pattern, each letter seems to be moving one step ahead. For instance, E becomes F and F becomes G. Following the same logic, A will become B and B will become C, resulting in the code 'BC'.

From the given codes, 'Sugar' is represented as 'Book', so reversing the coding, 'Book' is 'Salf', and 'Salt' is 'Sweet'. Hence, 'Sugar' is what we read.

The pattern here is a reversal of the letters. So, 'HEAR' would be coded as 'RAEH', but when the letters E and A are interchanged, the answer becomes 'Reah'.

To solve this coding question, let's analyze the pattern between the letters in 'MKH' and 'NPS':

1. M to N: The position of M is 13, and the position of N is 14. So, it’s +1.
2. K to P: The position of K is 11, and the position of P is 16. So, it’s +4
3. H to S: The position of H is 8, and the position of S is 19. So, it’s +11.

Now, let's apply the same pattern (+1, +5, +11) to 'DFJ':

1. D + 1 → E
2. F + 4 → K
3. J + 11 → U

So, 'DFJ' will be coded as EKU.

The pattern seems to be moving each letter one step backward. So, applying this to 'LL', the code will be 'KK'.
