▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

There are 120 boys and 57 girls in a school if 5% of the boys leave and no new students are admitted what percentage of the whole school will be girls

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Solution:-

• Number of Girls is 57
• Number of Boys is 120

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Girl Left 5% of 120

$\longrightarrow\sf \frac{5}{100}×120\\ \\ \longrightarrow \sf \frac{600}{100}=6$

Girl remaining 120-6= 114

Total Students now left =114+57= 171

Now percentage of Boys of Total Students

$\sf \longrightarrow\frac{57}{171}×100\\ \\ \sf \longrightarrow \frac{5700}{171}=33.33\%$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Boys is 33.33% of Total Students.
