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 vowels?

Zero

Note:

Vowels : a, e, i, o, u

Consonants (the rest of the letters in the alphabet) : b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y and z

Now, ATQ

M D E K 7 B I 4 M J N E 7 6 Z U V W I 3 H 4 F

There are total 6 numbers are in the given series.

Now, lets take the pairs from the series which contains a numbers which is immediately preceded by a alphabet and immediately followed by a alphabet.

K 7 B,

I 4 M,

I 3 H,

H 4 F

As, we can see from the above pairs, there is no such numbers which is followed by a vowel.

Hence, the correct answer is Zero.
