Let the number of students in the class be x
Given that
 \frac{25}{54} of the total class are girls

No. of girls =  \frac{25x}{54}
No. of boys = 1 - \frac{25}{54}
                   =  \frac{54-25}{54}
                   =  \frac{29}{54}
No. of boys =  \frac{29x}{54}
But given that, the number of boys = 2030
  \frac{29x}{54} = 2030

x = 2030 * \frac{54}{29}

x = 70 * 54 = 3780

No. of girls =  \frac{25x}{54}

                  =  \frac{25*3780}{54}
                  =  1750
