Explanation : The pattern of coding is such that each
letter has been allotted the value of 2 letters following
the sequence, i.e., A = BC, B = CD, C = DE, etc. Hence,
the word GRACE will be coded as ‘HISTBCDEFG’.
Therefore, option (a) is the answer.
Explanation : Refer to alphabet series in Table 5.1 starting
from the L.H.S. pair, E is the antecedent of F and G is
the precedent of F. We get EG as code for F; HJ as code
for I; and so on.
Similarly, EGDFDFKM is the code for FEEL. F is
coded as EG with its precedent and antecedent letters. Similarly, ‘I’ is coded as HJ and L as KM. Hence,
EGDFDFKM stands for FEEL. Therefore, option (b) is
the correct answer.
