Mettl Numerical Reasoning 5 — Questions and Answers
Question 1: A company spends $18,000 on advertising and generates $270,000 in sales. If they increase ad spend by 25%, and ROI remains constant, what will the new sales figure be?
- $295,000
- $312,500
- $325,000
- $337,500 (Correct answer)
Correct answer: $337,500
ROI ratio = 270,000/18,000 = 15; new ad spend = $22,500; new sales = 22,500 × 15 = $337,500.
Question 2: A data set has values: 14, 18, 11, 22, 15, 18, 11. What is the mode?
- 11 and 18 (Correct answer)
- 15
- 18
- 11
Correct answer: 11 and 18
Both 11 and 18 appear twice — more than any other value — making this a bimodal dataset.
Question 3: A ratio table shows output per machine per hour: Machine A=45 units, Machine B=60 units. How many hours will it take both machines working together to produce 945 units?
- 7 hours
- 9 hours (Correct answer)
- 10.5 hours
- 12 hours
Correct answer: 9 hours
Combined rate = 45 + 60 = 105 units/hr; time = 945 ÷ 105 = 9 hours.
Question 4: Currency exchange: 1 USD = 0.92 EUR. A European company buys goods worth $75,000. How much does it cost in euros?
- €68,250
- €68,900
- €69,000 (Correct answer)
- €70,500
Correct answer: €69,000
75,000 × 0.92 = 69,000 euros.
Question 5: A table shows expenses for three departments: HR=$32,000, IT=$57,000, Operations=$41,000. If the budget is cut by 12% across the board, what are the new IT department expenses?
- $48,160
- $50,160 (Correct answer)
- $52,000
- $54,000
Correct answer: $50,160
$57,000 × (1 − 0.12) = $57,000 × 0.88 = $50,160.
Question 6: A number series: 100, 95, 85, 70, 50, __ . What is the next number?
- 30
- 25 (Correct answer)
- 20
- 35
Correct answer: 25
Differences decrease by 5: −5, −10, −15, −20, −25; next term = 50 − 25 = 25.
Question 7: A graph shows monthly website visits (thousands): Jan=42, Feb=46.2, Mar=50.82. If the growth rate is constant, what will May's traffic be (in thousands, rounded to 2 decimal places)?
- 55.90
- 61.49 (Correct answer)
- 67.64
- 59.00
Correct answer: 61.49
Growth rate = 10% per month; Apr = 50.82 × 1.10 = 55.902; May = 55.902 × 1.10 ≈ 61.49.
