The ratio of boys and girls in a school is 9:5.If the total number of students in the school is 1050.Then number of boys is

675

650

600

550

Let the ratio be 'R'

Total number of students = 1050

Then,

9R + 5R = 1050

14R = 1050

=> R = 75

The number of boys = 9R = 9 x 75 = 675

Hence, option 1 is the correct answer.
