Answer 1

let total number of students be x.
75% of x is equals to 1500.
x is equal to 2000. then number girls is equals to 2000-1500=500.

Answer 2

Given:

Total number of boys = 1500

The percentage = 75%

To Find:

The number of girls

Solution:

Let the total number of students be = x

Therefore,

75% of x = 1500

75x/100 = 1500

x =  1500 × 100 / 75

x = 20 × 100

x = 2000

Now, since boys are = 75%

Thus, girls will be = 100-75

= 25%

Therefore, number of girls

= 25% of 2000

= 25/100 × 2000

= 2000/4

= 500

Answer: The total number of girls is 500.
