Answer 1

Answer:

1710

Step-by-step explanation:

this is simple

see given ratio of no. of girl to boys = 9:10

let no of girls be 9x and no. of boys be 10x

now given the total no. of boys = 900 which is equal to 10x

=> 10x = 900

=>     x = 900/10

=>      x = 90

now the no of girls = 9x  , where x = 90

so no. of girls = 9(90)

                       = 810

therefore total no. of students are

810 + 900

= 1710
