Given below are four combinations (i), (ii), (iii), (iv) of five letters. In each combination, you have to arrange the letters as per the English alphabetical order from left to right. Then in each combination, the first letter from the right end is numbered as I, the second letter from the right end is numbered as II, and so on. Hence, in each combination I, II, III, IV, and V will denote the position of the letters from the right end.
(i) WUBBS
(ii) OOIAA
(iii) LNKOO
(iv) LLELL
From each of the given words, the letters, which are at the same position, are clubbed together. The letters at each position (I, II, III, IV, V) will form a four-letter meaningful English word if taken in order of combination (i), (ii), (iii), (iv) respectively such that at least two letters are same but not consonant?
