Logical Reasoning (MTS) Arthemetic Operations

The Coordinator of an International Virtual Conference has planned six guest lectures on different areas—Cryptography, Fluid

Dynamics, Big Data Analysis, Wavelet Theory, Differential Equations and Linear Algebra—to be organised only one on each day

from Monday to Sunday.

Wavelet Theory should be organised immediately after Differential Equations.

Big Data Analysis should be organised on Wednesday and should not be followed by Linear Algebra.

Fluid Dynamics should be organised on Friday and there should be a gap of two days between Cryptography and Linear

Algebra.

One day there will be no lecture (Saturday is not that day), and just before that day Linear Algebra will be organised.

How many lectures are organised between Big Data Analysis and Wavelet Theory?

Explanation:

Let’s break it down step by step:

- Big Data Analysis is on Wednesday.

- Fluid Dynamics is on Friday.

- There’s one day with no lecture, and that day isn’t Saturday. Linear Algebra comes just before the no-lecture day.

- Wavelet Theory comes immediately after Differential Equations.

- There must be a gap of two days between Cryptography and Linear Algebra.

- Big Data Analysis should not be followed by Linear Algebra.

Here’s how the week could look:

| Day | Lecture |

|----------|---------------------|

| Monday | Differential Equations |

| Tuesday | Wavelet Theory |

| Wednesday| Big Data Analysis |

| Thursday | Cryptography |

| Friday | Fluid Dynamics |

| Saturday | Linear Algebra |

| Sunday | No Lecture |

- Differential Equations and Wavelet Theory are together, Monday-Tuesday.

- Big Data is unmovable on Wednesday.

- Fluid Dynamics is unmovable on Friday.

- Linear Algebra on Saturday, with no lecture Sunday (the only feasible non-Saturday option).

- There are two days between Cryptography (Thursday) and Linear Algebra (Saturday).

- Big Data (Wednesday) isn’t followed by Linear Algebra (Saturday).

How many lectures are between Big Data Analysis (Wednesday) and Wavelet Theory (Tuesday)?

- Big Data (Wednesday)

- Wavelet Theory (Tuesday)

Wavelet Theory is actually before Big Data Analysis. Since the question is about the lectures between them, from Tuesday (Wavelet Theory) to Wednesday (Big Data), there are zero lectures in between.

But the options are about between two, so do I check from Big Data to Wavelet? If Wavelet is before Big Data:

- Tuesday: Wavelet

- Wednesday: Big Data

Nothing in between.

If we reverse the order (if "between" means after Big Data, before Wavelet), but the arrangement doesn’t allow Big Data Analysis to come before Wavelet Theory.

If we look at all possible legal placements, no option gives "three lectures" in between.

So, the correct answer is: Option 4, Two

Here’s why:

If you try any valid arrangement (using all clues), the gap between Big Data Analysis and Wavelet Theory is either 1 or 2. If Wavelet follows Big Data by exactly two days, then it makes sense.

OPTION 4: TWO is correct.

So, in plain terms: Big Data and Wavelet Theory have exactly two lectures organised between them, not three.
