  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?

    Answer: $337,500

    ROI ratio = 270,000/18,000 = 15; new ad spend = $22,500; new sales = 22,500 × 15 = $337,500.

  2. A data set has values: 14, 18, 11, 22, 15, 18, 11. What is the mode?

    Answer: 11 and 18

    Both 11 and 18 appear twice — more than any other value — making this a bimodal dataset.

  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?

    Answer: 9 hours

    Combined rate = 45 + 60 = 105 units/hr; time = 945 ÷ 105 = 9 hours.

  4. Currency exchange: 1 USD = 0.92 EUR. A European company buys goods worth $75,000. How much does it cost in euros?

    Answer: €69,000

    75,000 × 0.92 = 69,000 euros.

  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?

    Answer: $50,160

    $57,000 × (1 − 0.12) = $57,000 × 0.88 = $50,160.

  6. A number series: 100, 95, 85, 70, 50, __ . What is the next number?

    Answer: 25

    Differences decrease by 5: −5, −10, −15, −20, −25; next term = 50 − 25 = 25.

  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)?

    Answer: 61.49

    Growth rate = 10% per month; Apr = 50.82 × 1.10 = 55.902; May = 55.902 × 1.10 ≈ 61.49.
