10 points question ​

Answer 1

Let the total number of students be x.

Therefore, by the problem

40% of x = 450

or x = 450 X 100/40

or x = 1125

Therefore, the number of girls = 1125-450 = 675

Answer 2

Answer:

No. of boys = 40%

No. of girls = 60%

Given that no.of boys = 450

Let total no. of students be x

450=45/100*x

x = 1000

No. of girls = 1000 - 450

= 550
