HBRI HBRI - Hogan Business Reasoning Inventory Numerical Estimation and Approximation 1 — Questions and Answers
Question 1: A company's revenue grew from $4.8 million to $6.3 million over two years. Which is the closest approximation of the percentage increase?
- About 25%
- About 31% (Correct answer)
- About 15%
- About 45%
Correct answer: About 31%
The increase is $1.5M on a base of $4.8M, which is approximately 31.25%.
Question 2: A project team of 12 people completes a task in 8 days. Approximately how many days would it take a team of 9 people to complete the same task?
- About 9 days
- About 11 days (Correct answer)
- About 14 days
- About 6 days
Correct answer: About 11 days
Total work = 12 × 8 = 96 person-days; 96 ÷ 9 ≈ 10.7, which rounds to about 11 days.
Question 3: If a company spends $2,340 monthly on software subscriptions and negotiates a 15% discount, what is the best estimate of the annual savings?
- About $2,800
- About $4,200 (Correct answer)
- About $3,500
- About $1,800
Correct answer: About $4,200
Monthly savings ≈ $351; annual savings ≈ $351 × 12 ≈ $4,212, closest to $4,200.
Question 4: Sales data shows 3,450 units sold in Q1, 4,210 in Q2, and 3,890 in Q3. Which is the closest estimate of average quarterly sales?
- About 3,700 units
- About 3,850 units (Correct answer)
- About 4,000 units
- About 4,200 units
Correct answer: About 3,850 units
Sum = 11,550 ÷ 3 = 3,850 units per quarter on average.
Question 5: A manager estimates that 18% of 4,500 customer complaints require escalation. Which is the best approximation of the number of escalations?
- About 650
- About 810 (Correct answer)
- About 540
- About 900
Correct answer: About 810
18% of 4,500 = 0.18 × 4,500 = 810 escalations.
Question 6: A warehouse processes approximately 1,200 orders per day and operates 5 days per week. Which estimate best represents annual order volume (52 weeks)?
- About 250,000
- About 312,000 (Correct answer)
- About 175,000
- About 425,000
Correct answer: About 312,000
