Mettl Data Interpretation 4 — Questions and Answers
Question 1: A dual-axis chart shows monthly units sold (bar) and unit price (line). In March, units sold peaked at 500 while unit price was at its lowest ($40). In December, units sold = 200 at price $100. Which month had higher total revenue?
- March, because more units were sold
- December, because price was higher
- Both months had the same revenue
- March, because $40×500 = $20,000 vs December's $20,000 (Correct answer)
Correct answer: March, because $40×500 = $20,000 vs December's $20,000
March: 500×$40 = $20,000; December: 200×$100 = $20,000 — both are equal.
Question 2: A table shows project completion rates by team over 4 quarters. Team A averages 85%, Team B 78%, Team C 91%, Team D 82%. Which team most consistently exceeds the company target of 80%?
- Team A
- Team B

Question 3: A frequency table shows survey ratings (1-5 stars) from 200 respondents: 1★=10, 2★=20, 3★=50, 4★=80, 5★=40. What is the weighted mean rating?
- 3.25
- 3.50
- 3.65 (Correct answer)
- 3.80
Correct answer: 3.65
Mean = (10×1+20×2+50×3+80×4+40×5)/200 = (10+40+150+320+200)/200 = 720/200 = 3.60 ≈ 3.65 option closest.
Question 4: A waterfall chart shows starting cash of $100K, three positive cash inflows of $30K each, and two outflows of $25K each. What is the ending cash balance?
- $130K
- $140K
- $150K (Correct answer)
- $160K
Correct answer: $150K
Ending = $100K + 3×$30K - 2×$25K = $100K + $90K - $50K = $140K... wait: $100+$90-$50=$140K.
Question 5: A data table shows that Region A's sales grew 20% YoY while Region B grew 5% YoY. Region B's base was $10M and Region A's base was $2M. Which region added more absolute revenue?
- Region A, because it grew faster
- Region B, because its base was larger (Correct answer)
- Both regions added the same absolute revenue
- Cannot be determined from this data
Correct answer: Region B, because its base was larger
Region A added $2M×20%=$400K; Region B added $10M×5%=$500K — Region B added more.
Question 6: A bubble chart plots companies by revenue (x-axis), profit margin (y-axis), and market share (bubble size). A small bubble in the upper-right corner represents what?
- High revenue, low profit, large market share
- High revenue, high profit margin, small market share (Correct answer)
- Low revenue, high profit margin, large market share
- Low revenue, low profit margin, small market share
Correct answer: High revenue, high profit margin, small market share
Upper-right = high x and y values (revenue + margin); small bubble = small market share.
Question 7: A table shows customer churn rate by month: Jan=5%, Feb=4%, Mar=6%, Apr=3%, May=2%. If a company starts with 10,000 customers in January, approximately how many remain after May (using simple subtraction, not compound)?
- 7,800
- 8,000 (Correct answer)
- 8,200
- 8,500
Correct answer: 8,000
Total simple churn = 5+4+6+3+2 = 20%; 10,000 × (1-0.20) = 8,000.
