In each question below is given a group of letters followed by four combinations of digits/symbols numbered (1), (2), (3) and (4). You have to find out which of the four combinations correctly represents the group of letters based on the following coding system and the conditions that follow and mark the number of that combination as your answer. If none of the combinations correctly represents the group of letters, mark (5)
i.e. ‘None of these’ as your answer.
Conditions: (i) If the first letter is a consonant and the last letter is a vowel, their codes are to be interchanged. (ii) If both the first and the third letters are consonants, both are to be coded as ‘T’. (iii) If the first letter is a vowel and the last letter is a consonant, both are to be coded as the code for the consonant.
