Question

A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow. Study the given codes and conditions and answer the question that follows.
Note: If none of the conditions apply, then codes for the respective number/symbol to be followed directly as given in the table.

Number/Symbol3#8$7&6*4^29@
CodeBSDFGHJKLPRWM

Conditions:
i) If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged.
ii) If the first element is an odd number and the last an even number, the first and last elements are to be coded as @.
iii) If both the second and third elements are perfect squares, then the code of the second element will be the code for the third element.
What will be the code for the following group?
849@

The correct answer is

DLLM

Solution:

Step 1: Identify the default codes from the table.

  • 8 = D
  • 4 = L
  • 9 = W
  • @ = M

Default Code String: D L W M

Step 2: Check which conditions apply to the group "849@".

  • Check Condition (i): The first element is '8' (a number) and the last is '@' (a symbol). Condition (i) requires the first to be a symbol and the last to be a number. Therefore, Condition (i) does NOT apply.
  • Check Condition (ii): The first element is '8' (an even number). Condition (ii) requires the first to be an odd number. Therefore, Condition (ii) does NOT apply.
  • Check Condition (iii): The second element is '4' (a perfect square) and the third element is '9' (a perfect square). Because both the second and third elements are perfect squares, Condition (iii) APPLIES.

Step 3: Apply the matching condition.

According to Condition (iii), the code for the third element (9) will become the code of the second element (4).

  • The code for '4' is L.
  • Therefore, the code for '9' changes from 'W' to L.

Final Answer: The code for the group 849@ is DLLM.
