how can i tell that v is not radiologist ? (Question: 44380.3 )

how can i tell that v is not radiologist ?

Question:

DIRECTIONS: Study the following information carefully and answer the questions given below:


Seven specialist doctors P, Q, R, S, T, U and V visit a polyclinic on the four days – Tuesday, Wednesday, Friday and Saturday – in a week. At least one doctor but not more than two doctors visit the polyclinic on each of these days. Each of them is specialist of different fields – ENT, Orthopaedics, Paediatrics, Neurologist, Ophthalmologist, Radiologist and Oncologist, S visits on Friday with Radiologist, Paediatrician does not visit on Saturday nor with T and V. Oncologist U visits alone on Tuesday. Q visits on Wednesday and he is not Paediatrician. R visits on Wednesday. V is not Radiologist. Paediatrician visits with ENT specialist. Neurologist visits on Friday. P is neither orthopaedics nor Radiologist.

On which day of the week does T visit?
Options:
A) Wednesday.
B) Friday.
C) Saturday.
D) Wednesday or Saturday.
E) None of these.
Solution:

Ans-(b);

U is the Oncologist and he alone visits on Tuesday.

Q and R visit on wednesday.

S and Radiologist visit on Friday.

Since Neurologist visits on friday and not more than two doctors visit on a single day, so S is the neurologist.

Since V is not the radiologist, so V visits on saturday.

Since Paediatrician visits with ENT specialist and Q is not the paediatrician, so Q is the ENT specialist and R is the paediatrician.

Thus we get the schedule of visits as under:



Hence, T visits on friday.
