Given:
TEACHER' is written as 'VGCEJGT
Solution:
Decoding the code for the word ‘TEACHER’
T → +2 → V
E→ +2 →G
A→ +2 →C
C→ +2 →E
H→ +2 →J
E→ +2 →G
R→ +2 →T
So likewise ‘CHILDREN’ will be coded as:
C→ +2 → E
H→ +2 → J
I→ +2 → K
L→ +2 → N
D→ +2 → F
R→ +2 → T
E→ +2 → G
N→ +2 → P
So the code for ‘CHILDREN’ is ‘EJKNFTGP’
