Arrange the following letter groups in the order in which they would appear in an English dictionary.
1. Dehyoindrat, 2. Dehtionydra, 3. Detionhydra, 4. Detionbydra, 5. Dehydration
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 25143
In a dictionary, letter groups are compared letter by letter from the left; the first place where two groups differ decides which comes first.
All five groups begin with De; the third letters are h (Dehyoindrat, Dehtionydra, Dehydration) and t (Detionhydra, Detionbydra), so the three Deh- groups come first
Among the Deh- groups, the fourth letters are t (Dehtionydra) and y (Dehyoindrat, Dehydration), so Dehtionydra comes first
Dehyoindrat and Dehydration both begin with Dehy; the fifth letters are o and d, and d comes first, so Dehydration, then Dehyoindrat
Detionhydra and Detionbydra both begin with Detion; the seventh letters are h and b, and b comes first, so Detionbydra, then Detionhydra
Order: Dehtionydra (2), Dehydration (5), Dehyoindrat (1), Detionbydra (4), Detionhydra (3)
The sequence is 25143.
