The letter - code for the Sth letter is
(S `div` 3) th letter for S = 3,6,9,12,15,18,21,24,(S + 13) th letter
for S = 1,2,3,4,5,6,7,8,10,11,13,,(S-b)th letter for S = 20,
22,23,25,26, where d= 7,6,4,3,2, and for S = 19,17,16,14,
the pattern of coding is -10,-7,-5,-2, respectively. In case of
decoding the inverse process is followed.
How many consonants are coded as Vowels in the letter- coding?

Options

A. Eight
B. Nine
C. Three
D. Four

Answer

d

Explanation

According to the question, the pattern of letter- coding is as follows:

`underset("consonant")(.B.)overset(code)rArr underset("vowel")(.O.)," "underset("consonant")(.C.)overset(code)rArr underset("vowel")(.A.)`
`.H.overset(code)rArr.U.," ".S. overset(code)rArr .I.`
So, the required no. of consonants =4.
