Arrange the following words as per the order in the dictionary:
1. BNFDBNRGTRFGJ, 2. BNFDBMSGTRFGJ, 3. BNFDBNSGTSFGJ, 4. BNFDBNSGRRFGJ, 5. BNFDBNSGTREGJ
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 21453
In a dictionary, words are compared letter by letter from the left; the first place where two words differ decides which comes first. With long strings, find the first letter where they part.
All five begin with BNFDB; the sixth letter is M in word 2 and N in the rest, so word 2 comes first
Words 1, 3, 4 and 5 begin with BNFDBN; the seventh letter is R in word 1 and S in words 3, 4 and 5, so word 1 comes next
Words 3, 4 and 5 begin with BNFDBNSG; the ninth letter is R in word 4 and T in words 3 and 5, so word 4 comes next
Words 3 and 5 begin with BNFDBNSGT; the tenth letter is S in word 3 and R in word 5, so word 5 comes before word 3
Order: 2, 1, 4, 5, 3
The sequence is 21453.
