Question

If55% of the students in a school are boys and the number of girls is 900, find the number of boys.​

Answer 1

Answer:

Let total no. of students be x

girls=900

=100%-55%

45%

Now,

45%*x=900

$\frac{45}{100} \times x = 900 \\ x = \frac{900 \times 100}{45} \\ x = 2000$

therefore total student=2000

boys=Total students -No. of girls

=2000-900

=1100
