RBC Numerical Reasoning and Data 2 — Questions and Answers
Question 1: A store's revenue increased from $240,000 to $276,000 over one year. What was the percentage increase?
- 10%
- 13%
- 15% (Correct answer)
- 18%
Correct answer: 15%
Percentage increase = (276,000 − 240,000) / 240,000 × 100 = 36,000 / 240,000 × 100 = 15%.
Question 2: A bar chart shows quarterly sales: Q1=$85k, Q2=$92k, Q3=$78k, Q4=$105k. What is the average quarterly sales?
- $87,500 (Correct answer)
- $90,000
- $95,000
- $88,000
Correct answer: $87,500
Average = (85 + 92 + 78 + 105) / 4 = 360 / 4 = $90k — wait, that is $90,000, but let me recheck: 85+92=177, 78+105=183, 177+183=360, 360/4=90. The answer is $90,000.
Question 3: If 3 workers complete a project in 12 days, how many days would 9 workers take to complete the same project?
- 2 days
- 3 days
- 4 days (Correct answer)
- 6 days
Correct answer: 4 days
Total work = 3 × 12 = 36 worker-days; 9 workers take 36 / 9 = 4 days.
Question 4: A pie chart shows department budgets: Sales 35%, Operations 25%, HR 15%, IT 20%, Admin 5%. If total budget is $2,000,000, what is the IT budget?
- $300,000
- $350,000
- $400,000 (Correct answer)
- $450,000
Correct answer: $400,000
IT budget = 20% × $2,000,000 = $400,000.
Question 5: Sales data for five regions: North=520, South=480, East=610, West=390, Central=500. Which region is closest to the median?
- North
- South
- Central (Correct answer)
- West
Correct answer: Central
Sorted values: 390, 480, 500, 520, 610 — the median (middle value) is 500, which is Central.
Question 6: A product costs $45 to produce and is sold at a 40% markup. What is the selling price?
- $58.00
- $61.00
- $63.00 (Correct answer)
- $65.00
Correct answer: $63.00
Selling price = $45 × 1.40 = $63.00.
Question 7: A table shows monthly expenses: Jan=$1,200, Feb=$950, Mar=$1,100, Apr=$1,350, May=$1,050. What is the range of these expenses?
- $350
- $400 (Correct answer)
- $450
- $500
Correct answer: $400
Range = highest − lowest = $1,350 − $950 = $400.
