Question

In a co educational school ,45% of the total students are girls . If there are 440 boys in the school , find the number of girls in school.

Answer 1

Answer:

360

Step-by-step explanation:

let total students be X

55% are boys = 440

therefore 0.55*X=440    so X=800

so no. of girls is 0.45*X = 0.45*800 = 360

Answer 2

Answer:

360 girls

Step-by-step explanation:

Let the total number of students be X

Given, 45% of X = girls, and no. of boys=440

We know that the remaining, 100% - 45% = 55% are boys.

55% of X = 440

(55/100) of X = 440

X = (440*100)/55 = 800 is the total no. of students.

No of girls = Total students - No. of boys = 800 - 440 = 360 girls

For verification:

45% of 800 = 360 (girls)

55% of 800 = 440 (boys)
