If CENTRAL is coded as BFMUQBK, then FRIENDS will be coded as _______
- AESHEMER
- BESHFMER
- CESHENER
- DESHFNER
Solution & Step-by-step Explanation
Let's examine the coding pattern for CENTRAL→BFMUQBK:
C
−1
B
E
+1
F
N
−1
M
T
+1
U
R
−1
Q
A
+1
B
L
−1
K
The pattern is an alternating shift of −1,+1,−1,+1,…
Applying the same logic to FRIENDS:
F
−1
E
R
+1
S
I
−1
H
1
+1
F
N

M
E
+1
F
S

R
Hence, the code is ESHFMER.
