little joe is in a marching band. the teacher asks the band to get into groups of 2, little joe alone. teacher asks for groups of 3, little joe alone again. teacher asks for groups of 4, little joe yet again alone. finally, asks for groups of 5, little joe finally fits in a group

how many ppl are in the class and can u find all possible answers?
 
It's got to be a multiple of 5, but not a multiple of 2, 3, or 4. 25 works, also 35, 55, etc. But also you need one less than the class size to be a multiple of 4 AND 3, therefore a multiple of 12.

25 still works, because 24 is a multiple of 12. But 35 and 55 don't work any more.

Personally I don't think the marching band would be much bigger than that so do you still need to search for more answers?
