Question

In a class of 40 students 18 are the girls. Find the percentage of boys in the class.

Answer 1

Answer:

Percentage of boys in the class $=55\%.$

Step-by-step explanation:

Total students in the class $=40$

Number of girls in the class $=18$

therefore number of boys in the class $=40-18=22$.

We have to find what percentage of $40$ is $22$?

Let it be $x\%$, then

$40*\frac{x}{100}=22\\\\x=22*\frac{100}{40} \\\\x=55$.

That is percentage of boys in the class $=55\%.$

Hence the answer

thank you

Answer 2

Step-by-step explanation:

Total no. of students= 40

Total girls= 18

Total boys= 40-18= 22

%of boys = No. of boys/ total no. of students X 100

22/40 X 100= 55%
