Question

There are 50 students in a class. Of these 30 are boys. Find the percentage of girls in the class. ​

Answer 1

Step-by-step explanation:

% =20×100/50

= 40%.....

Answer 2

Answer:

0.3*50=15 girls in the class

50–15=35 boys in the class

Unless of course this class doesn’t consist only of boys and girls.

It could, for instance, include adult women as well as girls. Maybe in fact ONLY women and girls are in the class, and there are zero boys.

Or it could be a dog training class and there could be 30% girls, 30% dogs belonging to girls, 20% dogs belonging to boys, and 20% boys, in which case only ten boys.

The possibilities are unlimited, all we can really say is that there are 15 girls, and that the other 35 students are not girls.
