Using the following code and key, decode the given coded word: Code : L X P Z J Y Q M N B ... Key : b a e s p r h i g t Coded word : Z B Y X M N Q B

According to given question,
L → b , X → a , P → e , Z → s , J → p , Y → r , Q → h , M → i , N → g , B → t
Replace the each capital from given relationship for Z B Y X M N Q B , We will get
Z → s
B → t
Y → r
X → a
M → i
N → g
Q → h
B → t
