Seven persons — P, Q, R, S, T, U, and V — visited a zoo on seven different days of the week starting from Monday to Sunday, but not necessarily in the same order. On which day did P visit the zoo? Statement I: Two persons visited between R and U. T visited two persons after U. V visited before P. Statement II: Q visited before S, who visited two persons after U. R visited on Monday. T visited after S. Statement III: S visited either on Monday or on Sunday. Q visited before V. As many persons visited before Q as after T. V visited after R but before U.

1. If the data in statement I alone is sufficient to answer the question, while the data in statement II and statement III alone is not sufficient to answer the question.
2. If the data in statement II alone is sufficient to answer the question, while the data in statement I and statement III alone is not sufficient to answer the question.
3. If the data given in both statements I and III together are sufficient to answer the question.
4. If the data given in both statements I and II together are sufficient to answer the question.

Correct answer: If the data given in both statements I and III together are sufficient to answer the question.

Solution

Statement I alone does not uniquely determine P’s day, and statement III alone is also insufficient. However, together they provide enough constraints on the positions of R, U, T, V, Q, and P to determine P uniquely, so the correct choice is the option stating that I and III together are sufficient.
