P, Q, R, S, T, U and V are seven professors. Each one teaches a different subject from Physics, Chemistry, Biology, English, Mathematics, Economics and Geography, but not necessarily in that same order. Each of them teaches one day each on the seven days of the week from Monday to Sunday not necessarily in the order. R teaches Biology on Friday. Q teaches Mathematics on the previous day of the day on which professor teaches Physics. V teaches on Sunday, but does not teach Chemistry or English. S teaches Economics on the previous day on which U teaches. P teaches Geography on Tuesday. T does not teach English.
On which day does U teach?
- Wednesday
- Thursday
- Friday
- Data inadequate
Answer and explanation
Correct answer: B - Thursday
P teaches on Tuesday, R on Friday and V on Sunday, leaving Monday, Wednesday, Thursday and Saturday. S teaches Economics the day before U, and the only free pair of consecutive days is Wednesday-Thursday (Monday is followed by Tuesday and Saturday by Sunday, both taken). So S is on Wednesday and U teaches on Thursday.
