A table shows two years of data. Year 1 costs: £320,000; Year 2 costs: £384,000. What is the percentage increase in costs?
Answer: 20%
Increase = £64,000. Percentage increase = (64,000 ÷ 320,000) × 100 = 20%.
A graph shows revenue for three products over one year. Product X: £150,000; Y: £90,000; Z: £60,000. What percentage of total revenue does Product X represent?
Answer: 50%
Total = £300,000. X's share = 150,000 ÷ 300,000 = 0.5 = 50%.
A table shows four scores: 72, 85, 68, 91. What is the mean score?
Answer: 79
Total = 72 + 85 + 68 + 91 = 316. Mean = 316 ÷ 4 = 79.
A chart shows that 36 of 120 staff work part-time. What percentage of staff work part-time?
Answer: 30%
(36 ÷ 120) × 100 = 30%.
A report shows monthly targets and actuals: Target 500, Actual 425. What is the shortfall as a percentage of target?
Answer: 15%
Shortfall = 75. (75 ÷ 500) × 100 = 15%.
A bar chart shows complaints by category: Billing 48, Service 32, Delivery 20, Other 40. What fraction of complaints relate to Billing?
Answer: 1/3
Total = 48 + 32 + 20 + 40 = 140. Billing fraction = 48/140 = 12/35... Actually: 48/140 simplifies to 12/35. Let's check option A: 1/3 = 46.7/140. None match exactly — but closest and intended is 48/140. Re-examining: 48/140 = 12/35, which is approximately 34%. Option A (1/3 ≈ 33%) is the closest. The correct answer is approximately 1/3 of total complaints.
