Answer:

Step-by-step explanation:

let the ratio of boys and girls be 5x and 4x

According to question,

5x+4x = 36

or, 9x= 36

x=4

number of boys = 5x

                            = 5·4= 20

number of girls = 4x

                         = 4.4=16

therefore the total no of boys is 20 ans girls is 16
