What is the overall percentage of marks obtained by Rahul?
Answer: C
Total marks obtained by Rahul = 90+60+70+70+80 = 370.
The maximum marks for each subject is 100. For 5 subjects, the total maximum marks = 500.
Overall Percentage = \(\frac{\text{Total Marks Obtained}}{\text{Total Maximum Marks}} \times 100\)
= \(\frac{370}{500} \times 100 = 74\)%.
