56%of the students of a school were boys and the rest were girls.afterwards ,24 boys left the school and 48 girls were admitted to the school as a result, the percentage of the boy students reduced to 50% of all the students. what is the present number of students?

Answer:

624

Step-by-step explanation:

Let say earlier students were = x

Boys = (56/100)×x = 0.56x

Girls = x - 0.56x = 0.44x

Now boys = 0.56x -24

Now girls = 0.44x + 48

Now boys are 50% so girls are also 100-50= 50%

Boys = girls

0.56x-24 = 0.44x +48

0.12x = 72

x = 600

So earlier students were 600

Current students = 600-24+48=624
