A medical representative visited the doctors P, Q, R, S, T, and U from Monday to Saturday - only one doctor per day. i. He visited U on some day before visiting R and T. ii. He visited P on the previous day of visiting S, but not on Thursday. iii. He did not visit either Q or S on the last day. iv. He visited Q just after U, but not on Tuesday. v) He visited U on Wednesday and T on the Last Day. Which are the two doctors he visited on the first two days?

Option 4 : P and S

Given:

A medical representative visited the doctors P, Q, R, S, T, and U from Monday to Saturday - only one doctor per day.

i) He visited P on the previous day of visiting S, but not on Thursday.

• This means he visited P before he visited S.

ii) He did not visit either Q or S on the last day.

ii) He visited Q just after U, but not on Tuesday.

iv) He visited U on some day before visiting R and T.

v) He visited U on Wednesday and T on the Last Day.

Thus, after arranging we get:

Thus we can say see visited P and S on the first two days.

Hence, the correct answer is "Option 4".
