Question

Q1. There are 1600 students in a school. Number of girl students are
600. Then find the ratio of:
(a) Number of girls to number of boys.
(b) Number of boys to total number of students​

Answer 1

30 is your answer

In the first case

Number of boys =660× 13/22 =390

Number of girls =660× 9/22 =270

Let the number of boys who left the school be x.

According to the question,

⇒ 390−x = 56/270+30 = 5/6

⇒390−x=360

⇒x=390−360

⇒x= 30

HOPE IT HELPS YOU !!!
