40% are boys

900 are girls.

To get the total number of boys, that will be number of boys, divided by hundred multiply by total number of girls

i.e 40÷100 * 900= 360, we have 360 boys, to know the number of student add 900 to the number of boys which gives you 1,260.

the total number of students in the school is 1,260
