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.

Number/ Symbal	1	%	8	4	∅	0	2	$	1	6	=	3	7	5
Code	A	E	I	0	U	P	R	T	V	X	Z	B	D	F

Conditions: (i) If the first element is a number and the last, a symbol, the codes for these two (the first and the last elements) are to be interchanged. ii) If the first element is an EVEN number and the last, an ODD number, the first and last elements are to be coded as &.
(iii) If both the second and the third elements are prime numbers, the third element is to be coded as the code for the second element.
Question: 2$373

According to the given information:

The given code is 2 $373

​Applying Conditions:

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

The first element is 2 (a number) and the last is 3 (a number), so this condition does not apply.

​Condition (ii): If the first element is an EVEN number and the last, an ODD number, the first and last elements are to be coded as &.

The first element is 2 (even) and the last element is 3 (odd), so both should be coded as &​

​New sequence: &$37&

Decoded sequence:

2 = &

$= T

3= B

7= D

3= &

So, the coded sequence for 2 $373 is &TBD&.

​Condition (iii): If both the second and the third elements are prime numbers, the third element is to be coded as the code for the second element.

​The second element $ is not a number, so this condition does not apply.

Thus, correct option is (d)​​​​​
