Question Discussion & Solution

(E_Name, Salary_in_Lakhs) is the key

(E_Name, Salary_in_Lakhs) → {E_ID, E_Age, E_mail}

E_Name: Nitesh is repeated

Check only for Nitesh

(Nitesh, 9) → (XE005, 24, nitestSE@123)

(Nitesh, R) → (XE023, 24, nitestCE@123)

Since right hand side is not same

Therefore, R cannot be equal to 9
