Question

A class has $50$ children$,$ out of which $12$ are girls$.$ What percentage of the class are boys$?$

Answer 1

Step $1:$ To find out the percentage of the boys in the class

It is given that$,$ total number of children $=50$

Number of girls $=12$

Number of boys $=$total children $-$number of girls

$=50-12$

Number of boys $=38$

Step $2:$ Now find the percentage of the boy

Required percentage$=\frac{38}{50}\times 100$

$=38\times 2$

$=76\%$

Hence, there are $76\%$ boys in the class.
