Question

80% of the students are boys and 400 are girls. How many students in the school
​

Answer 1

Answer:

Step-by-step explanation:

If 80℅ are boys then 100-80=20℅is girls

20℅of x=400

400*100/20= x I.e tota no of students

X= 2000

Answer 2

80%students are boys, so girls=100-80=20%

Let total number of children=x

So number of girls=20%of x=400

(20×x)/100=400

20×x=400×100

20×x=40000

x=40000/20

x=4000/2

x=2000
