Mu Sigma Placement Paper — Solved Questions

Section 1: Quantitative Aptitude

Section 2: Logical Reasoning

Question 14

A company's quarterly profits (in lakhs) are: Q1: 50, Q2: 60, Q3: 45, Q4: 65. Calculate the coefficient of variation (CV).

Solution: Mean = (50 + 60 + 45 + 65) / 4 = 220/4 = 55

Variance = [(50-55)² + (60-55)² + (45-55)² + (65-55)²] / 4 = [25 + 25 + 100 + 100] / 4 = 250/4 = 62.5

Standard Deviation = √62.5 = 7.91

CV = (SD / Mean) × 100 = (7.91 / 55) × 100 = 14.38%

Interpretation: A CV of 14.38% indicates moderate variability in quarterly profits.
