Explanation: (B) The question asks for the percent increase from 2013 to 2014, which is \(\frac{\text{Salary}_{2014} - \text{Salary}_{2013}}{\text{Salary}_{2013}}\). Statement 1 gives \(\text{Salary}_{2013}\), but not \(\text{Salary}_{2014}\). Not sufficient. Statement 2: Let \(\text{Salary}_{2012} = S\). \(\text{Salary}_{2013} = 1.2S\). \(\text{Salary}_{2014} = 1.3S\). Percent Increase = \(\frac{1.3S - 1.2S}{1.2S} = \frac{0.1S}{1.2S} = \frac{1}{12}\), which is a definitive percentage (approx. 8.33%). The ratio/percentage can be calculated without the actual salary figures. Therefore, statement 2 alone is sufficient.

- Zubin is a high school music teacher who teaches in classes VIII to XII. From all his students, he has found seven to be exceptionally talented, and believes that if groomed properly, they will be big stars someday. The students are Bappy, Muhit, Sabbir, Bobby, Zakir, Tonmoy, and Zofen. He plans to tutor each of them personally outside the class once a week, and has set aside an hour each day from Sunday to Thursday from his personal schedule for this purpose. But he started facing some problems while preparing the full schedule, as the students are from different classes and have different schedules of their own. He summarized the scheduling constraints as follows; Zakir's lesson must be on the day immediately before the day of Zofen's lesson. Muhit is the only student Interested in clarinet, so he needs to be taught in a separate lesson. Bobby's lesson must be on an earlier day than Sabbir's lesson. Only two of the lessons can be for two students, but those two joint lessons cannot be on consecutive days. If Zubin wants to schedule the two joint lessons as early in the week as possible, and wants to tutor Zakir and Zofen as late in the week as possible, Zubin could schedule Bappy's lesson-
