Key Questions & Solutions:
Q1: Which product has the highest average sales across all quadrants?
Solution:
Calculate average for each product:
A: (100+120+150+180)/4 = 140
B: (150+140+130+160)/4 = 145
C: (200+180+170+190)/4 = 185
D: (120+130+140+150)/4 = 145
E: (180+160+200+170)/4 = 175
Answer: Product C (Average = 185).
Q2: In which quadrant did Product E witness the maximum % increase in sales compared to the previous quadrant?
Solution:
Calculate % increase for each quadrant:
Q2 vs Q1: [(160-180)/180] × 100 = -11.11% (Decrease)
Q3 vs Q2: [(200-160)/160] × 100 = 25%
Q4 vs Q3: [(170-200)/200] × 100 = -15%
Answer: Q3 (25% increase).
2. Logical Reasoning (LR) Section
Question Type: Circular Arrangement (5 People at a Table)
Conditions:
A sits opposite to C.
B is adjacent to E but not to D.
D sits next to C.
E is not between A and B.
Solution:
Step 1: Draw a circle with 5 seats (Positions 1–5).
Step 2: From condition 1, place A and C opposite each other (e.g., A at 1, C at 3).
Step 3: B must be adjacent to E (condition 2). Possible pairs: B-E at positions 2-5 or 4-5.
Step 4: D must sit next to C (condition 3). Since C is at 3, D can be at 2 or 4.
Step 5: Ensure E is not between A and B (condition 4).
Final Arrangement (Positions 1–5, clockwise):
A
D
C
E
B
Verification:
A opposite C ✔️
B adjacent to E (positions 5 & 4) ✔️
D adjacent to C (positions 2 & 3) ✔️
E not between A and B ✔️
Answer: Order (clockwise): A, D, C, E, B.
3. Tips for Attempting DILR in 60 Minutes
DI: Skim tables/charts first; focus on key values (maxima, minima, averages).
LR: Draw diagrams; use elimination for constraints.
Time Management: Allocate 30 mins to DI and 30 mins to LR.
Final Score Target: Aim for 90% accuracy in DI (carry over 6 marks) and 80% in LR (carry over 5 marks).
Note: Always verify calculations and logical steps to avoid errors in high-stakes exams like CAT.
