  1. Total number of students in a class is 95. if the total number of girls in the class is 45, then the ratio of total number if boys to total number girls is
    1. 9:10
    2. 7:8
    3. 10:9
    4. 9:11
  1. Correct Option: C

    Let the total number of boys in the class be x.
    Then, according to the question,
    x + 45 = 95
    x = 95 - 45 = 50

    Hence, the required ratio of total number of boys to total number of girls = B:G = 50:45 = 10:9
