Select the correct option
A) 243 B) 265 C) 375 D) 390 E) 400
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   375
