​In this question, a group of numbers/symbols is coded using letters as per the table given below and the conditions which follow. The correct combination of codes following the conditions is your answer.

(i) If the second element is an odd number and the last element is an even number, the codes for these two (the second and the last elements) are to be interchanged.
(ii) If the third element is an even number and the fifth element is a symbol, the codes for these two (the third and the fifth elements) are to be interchanged.
(iii) If the fifth element is a symbol and the sixth element is also a symbol, both these elements (the fifth and the sixth elements) are to be coded as R

Question: E 75% & 4%8​​​

(i) If the second element is an odd number and the last element is an even number, the codes for these two (the second and the last elements) are to be interchanged. (Follows)

From the first condition second element is odd number(7) & last element is even number (8)

then code of 7 is S interchanged with the code of 8 which is A.

(ii) If the third element is an even number and the fifth element is a symbol, the codes for these two (the third and the fifth elements) are to be interchanged.(Not followed)
(iii) If the fifth element is a symbol and the sixth element is also a symbol, both these elements (the fifth and the sixth elements) are to be coded as R.(Not followed)​

Question: E 7 5 % & 4% 8

then, code for given expression:

Thus, Option D is the correct answer.
