Answers:

Q.A

  1. 2
    Required Average = (76 + 84 + 66 + 72 + 88 + 64)/6 * 150/100 = 112.5
  2. 2
    Required Average = (66 + 72 + 78 + 80 + 68 + 74)/6 * 75/100 = 54.75
  3. 1
    Total marks obtained by D in Biology, Maths and English together = 68% of 100 + 72% of 150 + 66% of 50 = 209
    Total marks obtained by F in Biology, Maths and English together = 79% of 100 + 64% of 150 + 80% of 50 = 215
    Required ratio = 209 : 215
  4. 5
    Required % = 66% of 150/(56% of 75 + 78% of 75 + 71 %of 100 + 66% of 150 + 86% of 50 + 70 % of 50) * 100 = 28% (approx)
  5. 5
    Total marks obtained by ‘B’ in all the subjects together
    = 76% of 75 + 72% of 75 + 65% of 100 + 84% of 150 + 74% of 50 + 75% of 50
    = 376.5
  6. B
  7. D
  8. D
  9. B
