There are 760 students in a school. The ratio of boys and girls in this school is 3:5. Find the total of girls & boys are there in this school?  Answers:
A) 320 B) 345 C) 425 D) 475 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 760. Hence   3x + 5x = 760   Solve for x   8x = 760   x = 95   Number of boys   3x = 3 × 95 = 285   Number of girls   5x = 5 × 95 = 475   475
