      are 40% boys. The total number of girls who took admission in B.Sc C.Sci and B.Com courses is what percentage of the total students admitted to the university? The following pie chart shows the distribution of the percentage of students in various courses at the university. The total number of students (boys and girls only) in the university is 7000.  
      A 25% Correct Answer Incorrect Answer
      B 29% Correct Answer Incorrect Answer
      C 23% Correct Answer Incorrect Answer
      D 27% Correct Answer Incorrect Answer

      Solution

      Total students = 7000
      B.Com students = 20% of 7000 = 1400
      B.Sc C.Sci students = 25% of 7000 = 1750

      Girls in B.Com = 60% of 1400 = 840
      Girls in B.Sc C.Sci = 60% of 1750 = 1050

      Total girls = 840 + 1050 = 1890
      Percentage = (1890 / 7000) × 100 = 27%
