How many floors are there between O and person who likes Blue?

J lives immediately above O and O lives on an odd numbered floor. There are 2 floors between J and N. And N does not live on lowermost floor. (so, we get following possible cases here). Case-1 There are 2 floors between O and one who likes Orange and it is also given that person who likes Orange, does not live on the top most floor. There is only 1 floor between O and yellow. Person who like Yellow does not live on lowermost floor. K lives on an even numbered floor and immediately above L. And it is also given that L does not like Yellow. Only 1 floor is between L and Black. One who likes Brown lives on an even numbered floor immediately above the one who likes Green and Q lives immediately below the one who likes Green.

One who likes blue lives on an even numbered floor. M does not live on an odd numbered floor. After filling the remaining data, we get:
