To find the overall percentage for students A and G, we need to calculate the total marks obtained by each student across all subjects and divide it by the total maximum marks possible for all subjects, then multiply by 100.

Student A Overall Percentage Calculation

First, calculate the actual marks obtained by Student A in each subject:

• English: \( 0.80 \times 150 = 120 \)
• Economics: \( 0.50 \times 130 = 65 \)
• Sociology: \( 0.80 \times 120 = 96 \)
• Philosophy: \( 0.60 \times 100 = 60 \)
• Psychology: \( 0.70 \times 60 = 42 \)
• IT: \( 0.80 \times 40 = 32 \)

Total marks obtained by Student A = \( 120 + 65 + 96 + 60 + 42 + 32 = 415 \)

Total maximum marks = \( 150 + 130 + 120 + 100 + 60 + 40 = 600 \)

Overall percentage for Student A = \( \frac{\text{Total Marks Obtained}}{\text{Total Maximum Marks}} \times 100 \)

Overall percentage for Student A = \( \frac{415}{600} \times 100 \approx 69.17\% \)

Student G Overall Percentage Calculation

Next, calculate the actual marks obtained by Student G in each subject:

• English: \( 0.60 \times 150 = 90 \)
• Economics: \( 0.35 \times 130 = 45.5 \)
• Sociology: \( 0.50 \times 120 = 60 \)
• Philosophy: \( 0.70 \times 100 = 70 \)
• Psychology: \( 0.70 \times 60 = 42 \)
• IT: \( 0.70 \times 40 = 28 \)

Total marks obtained by Student G = \( 90 + 45.5 + 60 + 70 + 42 + 28 = 335.5 \)

Total maximum marks (same for all students) = \( 600 \)

Overall percentage for Student G = \( \frac{\text{Total Marks Obtained}}{\text{Total Maximum Marks}} \times 100 \)

Overall percentage for Student G = \( \frac{335.5}{600} \times 100 \approx 55.92\% \)

Therefore, the overall percentages are approximately 69.17% for Student A and 55.92% for Student G.
