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 from second half of the
original alphabet series in the letter coding?

Options

A. Nine
B. Twelve
C. Eleven
D. Ten

Answer

c

Explanation

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

`underset("consonant")(.B.)" "overset(code)rArr" "underset("second half")(.O.,).D. overset(code)rArr .Q.`
`.G. overset(code)rArr .T.,.H.rArr.U.,`
`.J. rArr .W.,.K. rArr.X.,.M. rArr.Z.,.V. rArr .P.,`
`.W. rArr .S.,.Y. rArr.V.,.Z. rArr .X..`
So, the required no. of consonants = 11.
Note: Second half of alphabet series = N to Z = 14 to 26
