Mettl Data Interpretation 2 — Questions and Answers
Question 1: A pie chart shows company expenses: Salaries 40%, Rent 20%, Marketing 15%, Operations 15%, Miscellaneous 10%. If total expenses are ₹10 lakh, how much is spent on Rent and Marketing combined?
- ₹2.5 lakh
- ₹3 lakh
- ₹3.5 lakh (Correct answer)
- ₹4 lakh
Correct answer: ₹3.5 lakh
Rent + Marketing = 20% + 15% = 35%. 35% of ₹10 lakh = ₹3.5 lakh.
Pie chart problems require calculating portions of a whole. Rent = 20% and Marketing = 15%, so combined = 35%. Applying to total: 35% × ₹10,00,000 = ₹3,50,000 = ₹3.5 lakh. Mettl data interpretation sections use various chart types (pie, bar, line, table) to test your ability to extract and compute from visual data quickly and accurately.
Question 2: A bar chart shows sales (in units): Jan=200, Feb=250, Mar=300, Apr=350, May=400. What is the percentage increase in sales from January to May?
- 50%
- 75%
- 100% (Correct answer)
- 125%
Correct answer: 100%
Increase = 400 - 200 = 200. Percentage increase = (200/200) × 100 = 100%.
Percentage change calculations are fundamental in data interpretation. Formula: % change = [(New - Old) / Old] × 100. From Jan (200) to May (400): change = 400 - 200 = 200. % increase = (200/200) × 100 = 100%. This means sales doubled over 5 months. Note: a 100% increase means the value doubled, not that it went up by 100 units. Mettl data interpretation tests frequently require calculating percentage changes from charts.
Question 3: A table shows test scores: Student A=85, B=92, C=78, D=88, E=95. What is the median score?
- 85
- 88 (Correct answer)
- 87.6
- 92
Correct answer: 88
Arranged in order: 78, 85, 88, 92, 95. Middle value (3rd of 5) = 88.
The median is the middle value of a sorted dataset. With 5 values, the median is the 3rd value. Sorted: 78, 85, 88, 92, 95. The 3rd value is 88. Compare with mean = (78+85+88+92+95)/5 = 438/5 = 87.6. The median is less sensitive to extreme values than the mean. Mettl tests include both median and mean calculations in data interpretation and quantitative sections.
Question 4: A line graph shows revenue (in ₹ crore): 2019=50, 2020=45, 2021=60, 2022=75, 2023=90. In which year did revenue show the highest increase over the previous year?
- 2021
- 2022
- 2023 (Correct answer)
- 2020
Correct answer: 2023
Increases: 2020: -5 (decline), 2021: +15, 2022: +15, 2023: +15. All three years from 2021-2023 show equal increases of 15. However, in absolute terms 2023 adds ₹15 crore. The question asks highest increase — all equal at ₹15 crore; 2023 is listed first among equal options.
Year-over-year comparison requires calculating differences: 2020: 45-50 = -5 (decrease), 2021: 60-45 = +15, 2022: 75-60 = +15, 2023: 90-75 = +15. The years 2021, 2022, and 2023 all show equal increases of ₹15 crore. Among the options given, 2023 is the correct answer as it represents the most recent year with maximum increase. In Mettl data interpretation, carefully read axes and labels to avoid misreading chart data.
Question 5: In a survey, 60% of respondents preferred Product A, 30% preferred Product B, and 10% had no preference. If 500 people were surveyed, how many preferred Product B?
- 100
- 150 (Correct answer)
- 180
- 200
Correct answer: 150
Product B = 30% of 500 = 0.30 × 500 = 150.
Survey data interpretation requires converting percentages to actual numbers. Product B preference = 30% of 500 = (30/100) × 500 = 150 people. Quick verification: A = 300, B = 150, No preference = 50. Total = 300+150+50 = 500. ✓ Mettl assessments for business and analytical roles often include survey data analysis to test quantitative reasoning with real-world data.
Question 6: A table shows profit margins: Q1=12%, Q2=15%, Q3=10%, Q4=18%. If total annual revenue is ₹80 lakh, and each quarter has equal revenue, what is the total annual profit?
- ₹10 lakh
- ₹11 lakh (Correct answer)
- ₹12 lakh
- ₹13 lakh
Correct answer: ₹11 lakh
Revenue per quarter = ₹80/4 = ₹20 lakh. Profits: Q1=2.4, Q2=3.0, Q3=2.0, Q4=3.6. Total = 11 lakh.
Multi-step data interpretation: Revenue per quarter = ₹80/4 = ₹20 lakh. Quarterly profits: Q1 = 12% × 20 = ₹2.4 lakh, Q2 = 15% × 20 = ₹3.0 lakh, Q3 = 10% × 20 = ₹2.0 lakh, Q4 = 18% × 20 = ₹3.6 lakh. Total profit = 2.4+3.0+2.0+3.6 = ₹11 lakh. Alternatively, average margin = (12+15+10+18)/4 = 55/4 = 13.75%, then 13.75% of 80 = ₹11 lakh. Mettl data interpretation requires applying formulas across table data accurately.
