Question

if 40 percentage of the students are girls and number of boys are 600 then find the number of girls

Answer 1

Answer:

400

Step-by-step explanation:

Let x be the number of students in class.

So strength of boys = 60%

60% of x = 600

60x/100 = 600

x = 1000

So total students = 1000

Strength of girls = 1000*40/100

=400

Answer 2

Answer:

Step-by-step explanation:let no. of students be x

given:

no. of boys:600

%of girls:40

so,

40/100x+600=x   (40 per cent girls + 600 boys is total no. of students)

2/5x=600=x

600=3x/5

600x5=3x

3000=3x

x=3000/3

x=1000

therefore no. of  students =1000
