Question

Refer to the following letter series and answer the question that follows. Counting to be done from left to right only.
(Left) A Z I O J H I S S B M U J A W K M Z N B G (Right)
How many such vowels are there each of which is immediately preceded by a
consonant and also immediately followed by a consonant?

The correct answer is
Three

Understanding the Letter Series Pattern

The question asks us to analyze a given letter series: $A Z I O J H I S S B M U J A W K M Z N B G$. We need to find the number of times a specific pattern occurs. The pattern is a vowel that is immediately preceded by a consonant AND immediately followed by a consonant. We only count from left to right.

Defining Vowels and Consonants

First, let's clarify which letters are vowels and which are consonants in the English alphabet:

  • Vowels: A, E, I, O, U
  • Consonants: All other letters (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z)

Step-by-Step Analysis of the Series

Let's examine the series letter by letter, looking for the required pattern (Consonant - Vowel - Consonant). We'll denote Vowels as 'V' and Consonants as 'C'.

Series: $A Z I O J H I S S B M U J A W K M Z N B G$

  1. $A$: This is a vowel. It's at the beginning, so it has no preceding letter. The letter following it is $Z$ (Consonant). Pattern: (None)-V-C. Does not match.
  2. $Z$: Consonant.
  3. $I$: Vowel. Preceded by $Z$ (C), followed by $O$ (V). Pattern: C-V-V. Does not match.
  4. $O$: Vowel. Preceded by $I$ (V), followed by $J$ (C). Pattern: V-V-C. Does not match.
  5. $J$: Consonant.
  6. $H$: Consonant.
  7. $I$: Vowel. Preceded by $H$ (C), followed by $S$ (C). Pattern: C-V-C. This matches! (Count = 1)
  8. $S$: Consonant.
  9. $S$: Consonant.
  10. $B$: Consonant.
  11. $M$: Consonant.
  12. $U$: Vowel. Preceded by $M$ (C), followed by $J$ (C). Pattern: C-V-C. This matches! (Count = 2)
  13. $J$: Consonant.
  14. $A$: Vowel. Preceded by $J$ (C), followed by $W$ (C). Pattern: C-V-C. This matches! (Count = 3)
  15. $W$: Consonant.
  16. $K$: Consonant.
  17. $M$: Consonant.
  18. $Z$: Consonant.
  19. $N$: Consonant.
  20. $B$: Consonant.
  21. $G$: Consonant.

Final Count

By carefully examining the series and applying the condition (a vowel immediately preceded and followed by a consonant), we found three instances where this pattern occurs:

  • The vowel $I$ between $H$ and $S$.
  • The vowel $U$ between $M$ and $J$.
  • The vowel $A$ between $J$ and $W$.

Therefore, there are exactly three such vowels in the given series.
