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.

Conditions:
(i) If the first two elements are numbers and the last is a symbol, then interchange the codes for the second number and the last symbol.
(ii) If the second element is a symbol and the last is a symbol, then all the symbols are to be coded as C.
(iii) If the question has any number which is immediately preceded by a prime number, then interchange the codes of the first and last number appearing in the question.
Question: 79&8%#3

Correct option is A

Decode each element using the table.

Based on the given table:

Element 79&8%#3

Step 2: Apply the conditions one by one.

Condition (i):

"If the first two elements are numbers and the last is a symbol, then interchange the codes for the second number and the last symbol."

• The first two elements (7 and 9) are numbers, but the last element (3) is not a symbol (it’s a number).

• So, Condition (i) does not apply.

Condition (ii):

"If the second element is a symbol and the last is a symbol, then all the symbols are to be coded as C."

• The second element (9) is not a symbol, so Condition (ii) does not apply.

Condition (iii):

"If the question has any number which is immediately preceded by a prime number, then interchange the codes of the first and last number appearing in the question."

• 7 is a prime number, and it is immediately followed by 9.

• The first number in the sequence is 7 (D), and the last number is 3 (1).

• So, interchange the codes of 7 and 3:

o 7 → 1, 3 → D

Step 3: Final sequence after applying conditions on Element 79&8%#3

Original codes: DLFPAH1

After applying Condition (iii):  1LFPAHD
