Study the following arrangement carefully and answer the question given below:
R D A K 7 B I 3 M J E N 6 7 U Z V 1 W 3 H 4 F Y 8 P 6
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 followed by the consonant B
I 3 M — 3 is preceded by the vowel I
N 6 7 — 6 is followed by the number 7
6 7 U — 7 is followed by the vowel U, but preceded by the number 6, not a consonant
V 1 W — 1 is followed by the consonant W
W 3 H, H 4 F, Y 8 P — 3, 4 and 8 are each followed by a consonant
P 6 — the last 6 has nothing after it
No number has a consonant just before it and a vowel just after it, so the count is zero.
