A dual-axis chart shows revenue growing from $2.4M to $3.0M while costs grew from $1.8M to $2.4M. Which metric grew by a higher absolute amount?

Answer: Both grew by equal amounts

Revenue grew by $0.6M and costs also grew by $0.6M, so both increased by equal absolute amounts.

A data table shows that Machine A completes a job in 4 hours and Machine B in 6 hours. Working together, how long do they take?

Answer: 2.4 hours

Combined rate = 1/4 + 1/6 = 5/12 jobs/hr; time = 12/5 = 2.4 hours.

A trend table shows sales growth rates of 5%, 8%, 6%, and 9% over four years. What is the range of these growth rates?

Answer: 4%

Range = highest − lowest = 9% − 5% = 4%.

A table shows that Product X has a unit cost of $24 and sells for $36. What is the markup percentage on cost?

Answer: 50%

Markup % = (36 − 24) / 24 × 100 = 12 / 24 × 100 = 50%.

A graph shows monthly website visits: Jan=4,200, Feb=3,900, Mar=4,500, Apr=4,800. What is the overall change from January to April?

Answer: 600 visits increase

4,800 − 4,200 = 600 visits increase from January to April.

A pivot table shows total sales of $960,000 split equally among 4 regions. One region then loses 25% of its sales. What are that region's new sales?

Answer: $180,000

Each region = $960,000 / 4 = $240,000; after 25% loss = $240,000 × 0.75 = $180,000.

A data series shows values 14, 21, 28, 35, 42. What is the next value if the pattern continues?
