Jaya, Sushama, Rama, Dilip, Sudhir and Arun are doctors working in a hospital specialising in gynaecology, neurosurgery, paediatrics, orthopaedics, anaesthesia and intensive care, not necessarily in that order. What is Rama’s specialisation if the following conditions are to be met: • Jaya, Arun and Sushama work together. • Neurosurgeons always need the help of orthopaedic surgeons in the operation theatre. • Orthopaedic surgeries cannot happen on the same days that gynaecological surgeries happen. • Gynaecologists need paediatricians on standby during their operating hours. • Though Sudhir and Dilip work together, neither has ever met Sushma in the hospital. • All specialisations except intensive care need to work with Arun, the anaesthetist. • Doctors don’t work together other than as mentioned above.
