Question:

Lectures by industry experts have to be scheduled in Marketing, Finance, Operations, Organisational Behaviour and Information Systems. This has to be scheduled on a weekday (Monday to Friday). Only one lecture can be scheduled per day. Marketing cannot be scheduled on Tuesday as it is inconvenient for the expert. Expert for Finance is available only on Tuesday. As Information Systems and Finance are always considered important, Information Systems has to be scheduled immediatelyon the day following the Marketing lecture.

The Correct Option is D

Approach Solution - 1

To determine which lecture is scheduled on Monday, let's analyze the conditions and logically deduce the sequence of events:
  1. Marketing Restrictions: Marketing cannot be scheduled on Tuesday.
  2. Finance Restriction: Finance must be on Tuesday.
  3. Information Systems Condition: Information Systems must be scheduled immediately after Marketing.
  4. Organisational Behaviour Condition: Organisational Behaviour precedes the Marketing lecture.
Given our constraints, let's deduce:
  1. If Finance is scheduled on Tuesday, Marketing cannot be on Tuesday and must be scheduled on a day with room for both its required predecessor (Organisational Behaviour) and its successor (Information Systems).
  2. The only sequence that fits is:
    • Wednesday: Organisational Behaviour
    • Thursday: Marketing
    • Friday: Information Systems
This leaves us Monday and Tuesday. Since Finance must occur on Tuesday, the only available option for Monday is:

Operations

Therefore, the lecture scheduled on Monday is Operations.

Approach Solution -2

Three of the conditions lock Organisational Behaviour, Marketing and Information Systems into one unbroken block of three consecutive days, in that exact order, because Organisational Behaviour must sit immediately before Marketing and Information Systems must sit immediately after Marketing.

Since the week runs Monday to Friday, this three-day block can only start on Monday, Tuesday or Wednesday, giving three possible placements: Monday-Tuesday-Wednesday, Tuesday-Wednesday-Thursday, or Wednesday-Thursday-Friday.

Finance is fixed on Tuesday, and Marketing is barred from Tuesday, so no day of the block can fall on Tuesday at all, since Marketing sits in the middle of the block and would land there in the first two placements. This rules out both of those, leaving only Wednesday-Thursday-Friday as valid.

  1. Option A (Finance): Finance is fixed on Tuesday by its own condition, not Monday, so this is incorrect.
  2. Option B (Marketing): Marketing falls on Thursday, the middle day of the block, so this is incorrect.
  3. Option C (Information Systems): Information Systems falls on Friday, the last day of the block, so this is incorrect.
  4. Option D (Operations): With Wednesday, Thursday and Friday taken by Organisational Behaviour, Marketing and Information Systems, and Tuesday taken by Finance, the only day left for Operations is Monday, so this is correct.

The complete schedule is Monday: Operations, Tuesday: Finance, Wednesday: Organisational Behaviour, Thursday: Marketing, Friday: Information Systems.

the correct answer is Option D: Operations.
