Seven businessmen, G, H, I, J, K, L and M, travelled in the same month on different dates 4th, 8th, 11th, 14th, 17th, 22nd and 28th (but not necessarily in the same order).
L travelled the last. K travelled just after I but before J.
K travelled on the 11th.
Only two people travelled between K and M.
Exactly one person travelled between G and K, and K travelled after G.
On which date did M travel?
