  • Question

  • What is the total number of boys from Colleges E and F together?


  • Options
  • A. 215
  • B. 251
  • C. 283
  • D. 310

  • Correct Answer
  • 215 

    Explanation

    As per first graph,
    The number of students in Collage E = Total number of students x 7%
    As per second graph,
    The number of girls from College E = Total number of girls x 8%
    So number of boys in Collage E = The total number of students in Collage E - The total number of girls in Collage E.
    Number of boys from college E = 3500 x 7/100 - 1800 x 8/100
    Number of boys from college E = 35 x 7 - 18 x 8
    Number of boys from college E = 245 - 144 = 101
    Similarly for collage F also apply the same formula.
    Number of boys from college F = 3500 x 12/100 - 1800 x 17/100 = 420 - 306 = 114
    Hence, the total number of boys together in collage E and F = 101 + 114 = 215
