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 third and the fourth elements are prime numbers, the fourth element is to be coded as the code for the third element and vice-versa.

Question: 2675$! ​​​​

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. (Follows)

So, code of 2 is W and code of ! is Y.
(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 &. (Not follows)
(iii) If both the third and the fourth elements are prime numbers, the fourth element is to be coded as the code for the third element and vice-versa.(Follows)

So, code of  7 is C and code of 5 is E.

Question: 2675$! ​​

So, code of 2675$!  is WSCEUY.
