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/symbol | 1 | & | 2 | 9 | * | 7 | 3 | $ | 8 | 5 | 6 | 4 | @ | # |
| Code | B | F | I | K | A | V | S | U | E | Q | C | P | X | T |
Conditions:
(i) If the first element is a symbol and the second element is an even number, the first and the second elements are to be coded as E.
(ii) If both the first and the last elements are numbers, the codes for these two (the first and the last elements) are to be interchanged.
(iii) If the last element is a symbol, the element is to be coded as B.
