Answer 2

Answer:

WATCH is coded as "DZTKF".

Explanation:

Given,

GANGA is coded as DJNDJ

Here, we can observe that the middle letter for both the coded and the decoded word is the same. Thus, we need to keep it as it is.

Consider, the first two letters

GA $\Rightarrow$ DJ

Here, we can observe that,

G + 3 = J

A + 3 = D

Thus, these decoded letters are interchanged here.

Similarly,

For WATCH,

The middle letter "T" will remain unchanged.

Considering first two and the last two letters,

W + 3 = Z

A + 3 = D

T = T

C + 3 = F

H + 3 = K

Interchanging we get,

DZTKF

Hence, WATCH is coded as "DZTKF".
