Answer 1

Answer:

39

Step-by-step explanation:

boys: girls = 8:5

let the byes 8k and girls 5k

total number of students 8k+5k = 13k

let girl is x=5k then number of boys (5k+9)

number of students 5k+(5k+9) =10k+9

therefore

10k+9= 13k

or, 13k- 10k = 9

or , 3k=9

or , k= 3

then the total number of students is 13k = 13x3 = 39
