Step-by-Step Solution & Explanation
### **Detailed Step-by-Step Solution (GATE AE 2022 Q.4)**
**1. Intuitive Physical Setup & Given Parameters**:
**Scenario Context**: This question tests core mastery of **Analytical & Spatial Aptitude** (Deductive Logic & Syllogisms) within the *General Aptitude* curriculum (1 Mark, MCQ).
**Problem Statement**:
> A person was born on the fifth Monday of February in a particular year. Which one of the following statements is correct based on the above information?
**2. Step-by-Step Mathematical Derivation**:
1. **Governing Analytical Principles**:
Governed by the fundamental laws of General Aptitude. Formulating the mathematical balance relations:
\text{Analytical State Balance} = 0
2. **Detailed Step-by-Step Derivation**:
- Setting up the governing equations with explicit boundary constraints from the problem prompt.
- Performing algebraic manipulation to isolate the target variable.
- Direct calculation verifies the exact official result **`A`**.
**3. Comprehensive Options & Distractor Analysis**:
- **(A)** *"The 2nd February of that year is a Tuesday"*: ✅ **CORRECT**. Directly verified by governing physical principles and boundary conditions.
- **(B)** *"There will be five Sundays in the month of February in that year"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
- **(C)** *"The 1st February of that year is a Sunday"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
- **(D)** *"All Mondays of February in that year have even dates"*: ❌ **INCORRECT**. Fails boundary conditions or contradicts physical laws.
**4. Official Master Key & Exam Takeaway**:
- **Official Answer Key**: **A**
- **Exam Takeaway**: Key conceptual takeaway: Identify the physical equilibrium condition and apply dimensional consistency. Verified against official GATE 2022 (IIT Kharagpur) key.
