Arrange the following group of letters arranged in the dictionary from first to last.
(A) AMDNOR
(B) RANDOM
(C) ADMNOR
(D) ANMDOR
(E) ANDMOR
Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (C), (A), (E), (D), (B)
In a dictionary, words are compared letter by letter from the left; the first letter that differs decides the order.
(B) RANDOM begins with R; the other four begin with A, so RANDOM comes last
Second letters of the A-words: (C) ADMNOR has D, (A) AMDNOR has M, (E) ANDMOR and (D) ANMDOR have N; D comes before M, and M before N
So the order begins (C) ADMNOR, then (A) AMDNOR
(E) ANDMOR and (D) ANMDOR share AN; their third letters are D and M, so (E) comes before (D)
