Answer:   1100    Step-by-step explanation:   let the total no. of students be =x  45% of x =900  100 - 45 =55  therefore percentage of boys in school =55%  45/100 *x = 900  x =900*100/45  x = 2000    number of boys = 55% of 2000      55/100*2000  = 1100      therefore the no. of boys in school is 1100           hope this helps you☺️☺️☺️
