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 condition is your answer.
| Number/Symbol | 8 | = | 4 | 7 | @ | % | > | 2 | ! | ? | 5 | 3 | < | 9 |
| Code | Z | F | T | J | D | H | E | X | V | W | K | U | P | A |
Conditions:
(i) If the first element is a symbol and the last, a number, the codes for these two are to be interchanged.
(ii) If the first element is an odd number and the last, an even number, the first and last elements are to be coded as Ø.
(iii) If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
