  1. A UN field office spent $48,600 in Q1 and $52,200 in Q2. What is the percentage increase from Q1 to Q2?

    Answer: 7.41%

    Percentage increase = (52,200 − 48,600) / 48,600 × 100 = 3,600 / 48,600 × 100 ≈ 7.41%.

  2. A project budget of $250,000 is split among three teams in the ratio 3:5:2. How much does the team with the largest share receive?

    Answer: $125,000

    Total parts = 10; largest share = 5/10 × $250,000 = $125,000.

  3. If 1 USD = 0.92 EUR, how many USD does an employee need to convert to receive exactly 690 EUR?

    Answer: $750.00

    USD needed = 690 ÷ 0.92 = 750 USD.

  4. A logistics team drove 840 km over 4 days. On the fifth day they drove 20% more than the daily average. How many km did they drive on day 5?

    Answer: 252 km

    Daily average = 840 ÷ 4 = 210 km; day 5 = 210 × 1.20 = 252 km.

  5. An agency purchased 360 supply kits at $18 each and received a 15% bulk discount. What was the total cost after the discount?

    Answer: $5,508

    Full cost = 360 × $18 = $6,480; after 15% discount = $6,480 × 0.85 = $5,508.

  6. A field mission uses fuel at a rate of 12 liters per 100 km. How many liters are needed for a 750 km journey?

    Answer: 90 liters

    Fuel = (12 ÷ 100) × 750 = 90 liters.

  7. An organization's annual report shows staff costs of $1.2 million out of a total budget of $4.8 million. What percentage of the budget is staff costs?
