Sas an argument. The dictionaryScontains Name: [Eng, Math, Science] as key:value pairs.
The function displays the corresponding grade obtained by the students according to the following grading rules:
\[ \begin{array}{|c|c|} \hline \textbf{Average of Eng, Math, Science} & \textbf{Grade} \\ \hline \geq 90 & A \\ \hline < 90 \text{ but } \geq 60 & B \\ \hline < 60 & C \\ \hline \end{array} \]
Example: Consider the following dictionary: \[ S = \{\text{"AMIT"}: [92, 86, 64], \text{"NAGMA"}: [65, 42, 43], \text{"DAVID"}: [92, 90, 88]\} \] The output should be: \[ \text{AMIT} - B \\ \text{NAGMA} - C \\ \text{DAVID} - A \]- CBSE Class XII - 2024
