# Seven different exams - P, Q, R, S, T, U and V - are conducted on different days of the same week, i.e., from Monday to Sunday. Which exam was conducted on Wednesday?I. Two exams were conducted after exam P. Exam Q took place immediately after exam U. Exam Q was not conducted on Sunday or on Thursday. Exam T was not conducted immediately after exam P.II. Three exams were conducted before exam R. Exam S was conducted after exam P but before exam V. Exam Q was conducted after exam U and before exam T. Exam P was not conducted on Monday.

Solution

I : Two exams were conducted after exam P, => Exam P was held on Friday.

Exam Q took place immediately after exam U. Exam Q was not conducted on Sunday or on Thursday, => Exam Q was either conducted on Tuesday or Wednesday.

Also, Exam T was not conducted immediately after exam P.

Thus, we cannot find which exam was conducted on Wednesday, hence I alone is insufficient.

II : Three exams were conducted before exam R, => R was held on Thursday.

Exam S was conducted after exam P but before exam V and Exam P was not conducted on Monday, => P was conducted on Friday.

Exam Q was conducted after exam U and before exam T, => U was conducted on Monday.

Thus, Exam T was conducted on Wednesday.

$$\therefore$$ Statement II alone is sufficient.

=> Ans - (B)
