  • Options
  • A. 55
  • B. 117
  • C. 96
  • D. 78

  • Correct Answer
  • 78 

    Explanation

    Given : - According to question ,
    Total number of students in school = 400 students
    Ratio of boys and girls in school = 3 : 5
    Let us assume the ration is P.
    Number of boys = 3P
    Number of girls = 5P
    3P + 5P = 400
    8P = 400
    P = 50
    Number of boys = 3P = 3 x 50 =150
    Number of girls = 5P = 5 x 50 = 250
    % of the students speak only Hindi = 24%
    number of boys speak only Hindi = 18
    According to question ,
    The total number of girls speaking Hindi
    = 24% × Total number of students - number of boys speak only Hindi
    = 24% × 400 - 18
    = 96 - 18 = 78
