Each of W, X, Y, Z, A, B, and C has a wedding to attend on a different day of a week starting from Monday to Sunday. C has to attend the wedding immediately after A. Y has to attend a wedding on one of the days before B and W. Only Z has to attend a wedding before A. X has to attend a wedding on Friday. B does not have to attend a wedding on Sunday. On which day of the week does Y have to attend a wedding?

Explanation

Let's go through the information step-by-step to find the correct day for Y's wedding. Given Information: 1. Each of W, X, Y, Z, A, B, and C has a wedding on a different day from Monday to Sunday. 2. C has to attend a wedding immediately after A. 3. Y has to attend a wedding on one of the days before both B and W. 4. Only Z has to attend a wedding before A. 5. X has to attend a wedding on Friday. 6. B does not have a wedding on Sunday. Solution: Using the given information, let’s organize the days as follows: Since X’s wedding is on Friday, we know that X is scheduled for Friday. Since Z is the only person who has a wedding before A, Z must have a wedding on Monday, making A's wedding on Tuesday, with C on Wednesday (as C attends immediately after A). Since Y's wedding must be before B and W, and X is already set for Friday, Y's wedding can only be on Thursday. B cannot attend a wedding on Sunday, so B’s wedding must be on Saturday, leaving W for Sunday. Thus, the schedule is as follows: Monday - Z Tuesday - A Wednesday - C Thursday - Y Friday - X Saturday - B Sunday - W Answer: Y has to attend a wedding on Thursday.
