Insects and Spiders
 
Q As you know, one way to tell an insect from a spider is to count its legs. All insects have six legs, and all spiders have eight legs. So if some insects and spiders went to a dance, and there were 48 dancing legs, how many insects and how many spiders were at the dance?


 
A Four insects (24 legs) and three spiders (24 legs). No other combination will work.
