In each of these questions a group of letters is given followed by four combinations of digit/symbol lettered (1), (2), (3) and (4). Letters are to be coded as per the scheme and conditions given below. You have to find out the serial letter of the combination, which represents the letter group. Serial letter of that combination is your answer. If none of the combinations is correct, your answer is (5) i.e. 'None of these'.

Letter : E R J L N A Q D P U B F I K T H
Digit/Symbol : * $2 \copyright 9 6 \# 5 1 \% \$ \pounds 4 @ 7 3 8$
Conditions :
(i) If the first letter is followed by a vowel and the last letter is preceded by a consonant then the last letter is to be coded as the code for vowel following the first letter.
(ii) If there are no vowels in the group of letters then the codes for the fifth letter from the right and the fifth letter from the left are to be interchanged.
(iii) If the group of letters contains two vowels then the codes for both the vowels are to be interchanged.
