Question

Consider any eleven integer numbers, not necessarily distinct. Prove that one can always choose six of these integers whose sum is divisible by five.

Answer 1

But is this true? Suppose that the 11 numbers
are all 1. Then any 6 of them add up to 6, which
is not divisible by 5.

Answer 2

52845785496

5+6+4+8+2+5=30 30/5=6
7+8+5+9+6+5=40 40/5=8
