  • Question
  • For which course is the number of boys the minimum?


  • Options
  • A. A
  • B. C
  • C. E
  • D. F

  • Correct Answer


  • Explanation

    As per first graph,
    The number of students for course A = Total number of students x 20%
    As per second graph,
    The number of girls for course A = Total number of girls x 30%
    Number of boys in course 'A' = The number of students for course A - The number of girls for course A
    Number of boys in course 'A' = (1200 x 20/100 ) - ( 800 x 30/100 ) = 240 - 240 = 0
    Number of boys in course 'C' = (1200 x 5/100 ) - (800 x 2/100) = 60 - 16 = 44
    Number of boys in course 'E' = (1200 x 12/100 ) - 800 x 14/100 ) = 144 - 112 = 32
    Number of boys in course 'F' = (1200 x 13/100 ) - ( 800 x 14/100 ) = 156 - 112 = 44
    Hence, in course 'A' number of boys is minimum which is Zero.
