Answer:

In order to obtain a ratio of boys to girls equal to 3:5, the number of boys has to be written as 3 x and the number of girls as 5 x where x is a common factor to the number of girls and the number of boys. The total number of boys and girls is 600. Hence

3x + 5x = 600

Solve for x

8x = 600

x = 75

Number of boys

3x = 3 × 75 = 225

Number of girls

5x = 5 × 75 = 375
