Refer to the given letter series and answer the question that follows. Counting to be done from left to right only. (Left) T J C U J D C Y P S U V Y R T W K V U H Z (Right) How many such vowels are there, each of which is immediately preceded by a consonant and also immediately followed by a consonant?
One
Three
None
Two
Three
Scan the series for all vowels (A, E, I, O, U) first, then quickly check the immediate left and right neighbors to see if both are consonants.
Scan the series for all vowels (A, E, I, O, U) first, then quickly check the immediate left and right neighbors to see if both are consonants.
Identify Vowels in the Series
The given series is: T J C U J D C Y P S U V Y R T W K V U H Z. The vowels in this series are: 1st vowel is U (at position 4), 2nd vowel is U (at position 11), 3rd vowel is U (at position 19).
Validate Consonant-Vowel-Consonant Pattern
Check neighbors for each U: 1) U at pos 4: Preceded by C (consonant) and followed by J (consonant). This counts. 2) U at pos 11: Preceded by S (consonant) and followed by V (consonant). This counts. 3) U at pos 19: Preceded by V (consonant) and followed by H (consonant). This counts.
A: One is incorrect as we found three instances. C: None is incorrect as the pattern exists three times. D: Two is incorrect because it fails to account for all three valid occurrences.
B is correct because there are exactly three vowels (U at index 4, U at index 11, and U at index 19) that are flanked by consonants on both sides.
In such questions, list the positions of all vowels first to avoid missing any hidden in the middle of the string.
