In each question below is given a group of letters followed by four combinations of digits/symbols numbered (a), (b) , (c) and (d). You have to find out which of the combinations correctly represents the group of letters based on the coding system and mark the number of that combination as your answer. If none of the combinations correctly represents the group of letters, mark of the combinations correctly represents the group of letters, mark (e), i.e. "None of these" as your answer. {:("Letter",:,"W R A P G B M U S E F T N D"),("Digit/Symbol Code",:,"$ 8 ! 2 7 # 9 @ ? 5 "beta" 4 * 6"):} Conditions : (i) If the middle letter is a vowel, the codes for the first and fourth letter are to be interchanged.
