: Ji-hu lives on the even floor so the possible floor numbers for him are 2, 4, 6. Ji-hu. Ji-hu cannot live on floor 4 because due to it min-ho will live on floor number 1 and there will be no valid position for Woo-jin hence this possibility is canceled. Also If Ji-hu lives on floor number 6 then Min-ho lives on floor 3 and then Woo-jin lives on floor 2 and Kun-woo on floor 2 but then the position for Ji-hoon is not satisfied hence only condition which is valid for Ji-hu is to sit him at floor number 2.Only two person live between Ji-hu and Min-ho. 
Step 2: Woo-jin lives on even floor and rides Aprilia so the possibility for him are 4 or 6 but Kun-woo lives immediately below Woo-jin so he will live on floor number 4 and Kun-woo lives immediately below it and the person who ride Dueati sits immediately above Woo-jin and thus the arrangement will look as shown below 
Step 3:Joo-won does not lives on the floor number 1 so the only floor left for him is floor 6 and the only person left is Ji-hoon so he sits on floor 1.Joo-won rides KTM. Ji-hu doesn’t ride Harley-Davidson or Royal Enfield so he ride Benelli. Harley-Davidson and Royal Enfield is ride by Kun-woo or Ji-hoon (not necessarily in the same order).
