As per the given information, the one who sits immediate right of M likes Lucknow. M sits 2ndfrom one of the extreme ends. Only one person sits between M and L. Here we have two possible cases i.e. 
J sits 4th to the left of P, who sits adjacent to L. Only one person sits between O and P, who likes dehradun. 
More than three persons sit between J and O. K sits to the left of N. More than two persons sit between the one who likes dehradun and the one who likes Delhi. 
K is not an immediate neighbor of J. Here Case 1 gets eliminated. Neither M nor L likes noida. The one who likes Jaipur sits 3rd to the left of the one who likes noida. N does not like Pune. So the final arrangement will be,
