    The total number of boys = 105

    Step-by-step explanation:

    The ratio of boys to girls = 3: 4

    ⇒ For every 3 boys, there are 4 girls.

    Now, total number of students = 245

    Let the common ratio of boys to girls is k.

    So, 3k + 4k = 245

    or, 7k = 245

    ⇒ k = 245/7 = 35

    ⇒ k = 35

    Hence, the number of boys = 3k = 3 x 35 = 105

    and number of girls = 4k = 4 x 35 = 140
