At what time was the Digital Marketing class scheduled?
Statement I. International marketing class ended at 10.00 am which was preceded by Service Marketing.
Statement II. Rural Marketing was scheduled as the last class.
Statement III. International Marketing was immediately followed by Digital Marketing.

• A. I only
• B. II only
• C. I and II together or I and III together
• D. II and III together

Answer 1

The Correct Option is C

Let's determine at what time the Digital Marketing class was scheduled using the given statements:
Statement I: International Marketing class ended at 10.00 am, which was preceded by Service Marketing.
Statement II: Rural Marketing was scheduled as the last class.
Statement III: International Marketing was immediately followed by Digital Marketing.
First, analyze Statement I:
- International Marketing ended at 10.00 am.
- Therefore, International Marketing was from 9.00 am to 10.00 am.
- Service Marketing preceded International Marketing, so it must have been from 8.00 am to 9.00 am.
Next, analyze Statement II:
- Rural Marketing was the last class.
- Since the classes are consecutive and each class is one hour long, Rural Marketing must be from 11.00 am to 12.00 pm.
Now, analyze Statement III:
- International Marketing was immediately followed by Digital Marketing.
- Since International Marketing was from 9.00 am to 10.00 am, Digital Marketing must be from 10.00 am to 11.00 am.
Conclusion:
Using Statements I and II together:
- From Statement I, Service Marketing is from 8.00 am to 9.00 am, and International Marketing is from 9.00 am to 10.00 am.
- From Statement II, Rural Marketing is from 11.00 am to 12.00 pm.
- This leaves the only slot from 10.00 am to 11.00 am for Digital Marketing.
Using Statements I and III together:
- From Statement I, Service Marketing is from 8.00 am to 9.00 am, and International Marketing is from 9.00 am to 10.00 am.
- From Statement III, Digital Marketing follows International Marketing immediately, so Digital Marketing is from 10.00 am to 11.00 am.
Therefore, the correct answer is: C. I and II together or I and III together.

Answer 2

There are four one-hour classes back to back starting at 8:00 am, so the only four possible slots are 8-9, 9-10, 10-11 and 11-12. Instead of reasoning statement by statement in words, fill a timetable directly with each statement and check which combination pins down a single slot for Digital Marketing.

1. Option A (I only): Statement I fixes Service Marketing at 8-9 and International Marketing at 9-10 (since it ended at 10 am). That leaves 10-11 and 11-12 open for Digital Marketing and Rural Marketing, in either order. Digital Marketing could be at 10-11 or 11-12, so Statement I alone leaves two possible timetables. Not sufficient.
2. Option B (II only): Statement II only fixes Rural Marketing at 11-12. The other three subjects can be arranged in any order across 8-9, 9-10 and 10-11, so Digital Marketing could occupy any of three slots. Not sufficient.
3. Option C (I and II together, or I and III together): Filling the table with Statement I gives Service Marketing = 8-9, International Marketing = 9-10, leaving only 10-11 and 11-12 for Digital Marketing and Rural Marketing. Adding Statement II fixes Rural Marketing = 11-12, which forces Digital Marketing = 10-11, a single unique slot. Separately, filling the table with Statement I and adding Statement III (Digital Marketing immediately follows International Marketing) also forces Digital Marketing = 10-11 directly, without even needing Statement II. Either pairing pins down one unique timetable.
4. Option D (II and III together): Statement II fixes Rural Marketing = 11-12. Statement III says International Marketing is immediately followed by Digital Marketing, but without Statement I we don't know where International Marketing starts — the pair could be 8-9/9-10 or 9-10/10-11, giving two different timetables and two different times for Digital Marketing. Not sufficient.

Only pairing I with II, or I with III, pins Digital Marketing to a single, unique slot (10-11).

Therefore, the correct answer is I and II together or I and III together.
