 Class act (Posted on 2002-05-02)
31 students in a row were numbered 1,2,...,31 in order. The teacher wrote down a number on the blackboard.

Student 1 said "the number is divisible by 1",
Student 2 said "the number is divisible by 2",
and so forth...until
Student 31 said "the number is divisible by 31".

The teacher remarked: "Very well pups, but two of you gave a wrong statement, and those two sit besides each other". Determine those two.

I have found it... and i think my way is to long to write here... it's similar with the solution... by the way it gave me inspiration to make another similar problem... thanks theBal... nice for brain gym...

Yes, it's not to hard... but this problem have their own difficulty... i just like it... how about with higher number like 52.. i still working it now.. if there isn't exact solution... because i go to go now...
