Question

In a Co_educational school.. 45%of the total are girls.. If there are 440 boys in the school.... Find the number of girls.?​

Answer 1

No.of boys=440

Total%of girls=45

total%of boys=100-45=55%

Let the total number of student be x

55%of x=440

x=100×440/55=800

Total number of student=800 students.

Now,

Total %of girl=45%

No of total student=800

No of girls=45%of 800=360.

HENCE,

TOTAL NUMBER OF GIRLS IS 360

Answer 2

Given that :

In a coeducational school 45% of total students are girl.

Then, percentage of boys = 100 - 45 = 55%

Let, the number of total students be x

Now, according to the question :

x × 55/100 = 440

=> x = (440×100)/55 = 800

So, the total number of students will be 800

Number of girls :

800×45/100 = 360
