Answers:
Q1. 49.75
Average = 298.5/6 = 49.75
Average = 298.5/6 = 49.75
Q2. 338.5
Total marks = 75 * 0.56 + 75 * 0.66 + 200 * 0.55 + 50 * 0.76 + 150 * 0.66 = 338.5
Total marks = 75 * 0.56 + 75 * 0.66 + 200 * 0.55 + 50 * 0.76 + 150 * 0.66 = 338.5
Q3. 57%
Marks scored by B = 75 * 0.68 + 75 * 0.64 + 200 * 0.49 + 50 * 0.74 + 150 * 0.52 = 312
Reqd % = 312/550 x 100 = 56.27 ≈ 57%
Marks scored by B = 75 * 0.68 + 75 * 0.64 + 200 * 0.49 + 50 * 0.74 + 150 * 0.52 = 312
Reqd % = 312/550 x 100 = 56.27 ≈ 57%
Q4. 56%
Marks scored by Student C in Physics = 75 * 0.72 = 54
Marks scored by Student C in English = 150 * 0.64 = 96
Reqd % = 54/96 x 100 = 56.25% ≈ 56%
Marks scored by Student C in Physics = 75 * 0.72 = 54
Marks scored by Student C in English = 150 * 0.64 = 96
Reqd % = 54/96 x 100 = 56.25% ≈ 56%
Q5. 18
Total marks obtained by Student D. = (75 x 0.82) + (150 x 0.70) = 166.5
Total marks obtained by Student F. = (75 x 0.66) + ( 150 + 0.66) = 148.5
Difference = 166.5 – 148.5 = 18
Total marks obtained by Student D. = (75 x 0.82) + (150 x 0.70) = 166.5
Total marks obtained by Student F. = (75 x 0.66) + ( 150 + 0.66) = 148.5
Difference = 166.5 – 148.5 = 18
