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 are to be followed directly as given in the table.

Conditions:

i) If the first element is a number and the last a symbol, then the codes for these two (the first and the last elements) are to be interchanged.
ii) If the first and the last elements are odd numbers, then the first and last elements are to be coded as @.
iii) If both the second and third elements are perfect square roots, then the third element is to be coded as the code for the second element.
What will be the code for 5#64%?

Conditions:
i) If the first element is a number and the last a symbol, then the codes for these two (the first and the last elements) are to be interchanged. (Follows)

So, code of  5 → G and % → A

ii) If the first and the last elements are odd numbers, then the first and last elements are to be coded as @.

False, first and the last elements are not odd numbers.
iii) If both the second and third elements are perfect square roots, then the third element is to be coded as the code for the second element.

False, both the second and third elements are not perfect square roots.
Now, the code of 5#64% is G N P K A. 

​Thus, correct option is (c).
