K3 cannot sit at place no. 6, 5, 4 and 8. So, only place left for him is place no. 1. As K8 is an immediate neighbour of K3. So, K8 will sit either at place no. 8 or 2. The one who likes Rose sits either at place no. 4 or 2. Only three people sit between the one who likes Rose and the one who likes Marigold. So, the one who likes Marigold sits either at place no. 6 or 8. K6 sits second to the left of the one who likes Marigold. So, K6 sits either at place no. 4 or 6. Case-1
