Question

. In a school 25% teachers, 40% boys. What is the percentage of girls?​

Answer 1

Answer:

Percentage of boys and teachers= 65%

Percentage of girls = 100 -65

35%

Answer 2

Answer:

Let the number of boys be ‘x' and the number of girls be ‘y'.

Total number of students = x+y

According to question

25% of x + 40% of y = 32% of (x+y)

25x + 40y = 32 (x+y)

25x+40y = 32x+32y

40y-32y = 32x-25x

8y =7x

y=7x/8

Now percentage of number of boys with respect to total number of students = (x /x+y)×100=(x /x+7x/8)×100=(8/15)×100=53.33%

Hence correct answer is 53.33%.
