Question

There are 1600 students in a school. Number of girl students are 600. Then find the ratio of
number of grils to no. of bois.
no. of bois to total no. of nerds (student$)​

Answer 1

Step-by-step explanation:

let boys be X and girls be (60-x)

contribution by boys =X*(60-X)

contribution by girls =(60-X) *X

Total =1600

60X-X^2+60X-60X^2=11600

BY SOLVING QUADRATICALLY, WE GET

X=40,X=20

no. of boys can be 20 or 40

also no. of girls can be 20 or 40
