Study the following arrangement carefully and answer the question given below.
M D E K 7 B I 4 M J N E 7 6 Z U V W I 3 H 4 F
How many such numbers are there in the above sequence each of which is immediately preceded by a consonant and immediately followed by a vowel?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Zero
Only the numbers of the sequence are tested. For each one, look at its immediate neighbours: the element just before it must be a consonant and the element just after it must be a vowel (A, E, I, O, U).
K 7 B — 7 is preceded by the consonant K, but followed by the consonant B
I 4 M — 4 is preceded by the vowel I
E 7 6 — 7 is preceded by the vowel E
7 6 Z — 6 is preceded by the number 7
I 3 H — 3 is preceded by the vowel I
H 4 F — 4 is preceded by the consonant H, but followed by the consonant F
No number has a consonant before it and a vowel after it, so the count is zero.
