Answer: Hello there dude, let's solve it in English first:
the team has 4 integrants, Alfonso, Sandra, Jorge, and Luis:
We know that Luis answered more than Alfonso and less than Sandra
this means that S>L>A
we also know that Jorge answered less than Luis but more than Alfonso.
This means that L>J>A
Where each capital letter is the number of answers that each one answered.
the first relation is:
S>L>A
and the second is:
L>J>A
then we know that J is in between L and A, and S is bigger than L and A, so the biggest number is S.
This means that Sandra answered the biggest number of exercises.
Spanish now!
Ok, sabemos que Luis contesto mas que Alfonso y menos que Sandra, entonces la relacion entre ejercicios resueltos por cada uno es:
S> L > A
tambien sabemos que Jorge respondio menos que luis y mas que Alfonso, esto es
L>J>A
entonces el ordenamiento total seria:
S > L > J>A
lo que dice que Sandra es quien contesto mas ejercicios, seguida por Luis, Jorge y finalmente Alfonso
