In code language the following alphabets are coded in a particular way: A → ! B → @ C → # D → $ E → % F → ^ G → & H → * I → + O → = P → α R → β S → γ T → δ U → ∠ How is the word DEAR coded as?

According to given question,
A → ! , B → @ , C → # , D → $ , E → % , F → ^ , G → & , H → * , I → + , O → = , P → α , R → β , S → γ , T → δ , U → ∠
Replace the each capital from given relationship for DEAR , We will get
D → $
E → %
A → !
R → β
Hence , the required answer will be $ % ! β.
