Crossover Aptitude Test Data Interpretation: Charts/Graphs 5 — Questions and Answers
Question 1: A dual-axis chart shows revenue (left axis, bars) and headcount (right axis, line) over 4 years. Revenue doubles while headcount grows by 10%. What does this suggest?
- Productivity declined
- Revenue per employee decreased
- Revenue per employee increased (Correct answer)
- Headcount caused revenue to double
Correct answer: Revenue per employee increased
If revenue grows much faster than headcount, each employee generates more revenue — productivity increased.
Question 2: A cumulative frequency graph (ogive) shows 80% of students scored below 85. What does the 80th percentile represent here?
- 85% of students scored above 80
- The score at which 80% of students fall below (Correct answer)
- The average score of the top 20%
- A score that 20% of students achieved
Correct answer: The score at which 80% of students fall below
The 80th percentile is the score below which 80% of the data falls, which is 85 in this case.
Question 3: A bar graph shows energy consumption (MWh) by department: Production=500, Admin=100, R&D=200, Logistics=300. If the company reduces total energy by 10%, how much must be saved?
- 100 MWh
- 110 MWh (Correct answer)
- 120 MWh
- 130 MWh
Correct answer: 110 MWh
Total = 500+100+200+300 = 1,100 MWh; 10% of 1,100 = 110 MWh.
Question 4: A line graph has two lines that intersect in Year 3. Before Year 3, Line A is above Line B. After Year 3, Line B is above Line A. What occurred at Year 3?
- Both values became zero
- Line A's value exceeded Line B's
- Line B surpassed Line A
- The values became equal (Correct answer)
Correct answer: The values became equal
At the intersection point, both lines share the same value — they are equal at Year 3.
Question 5: A pie chart shows 6 equal sectors. Two adjacent sectors are shaded. What percentage of the chart is shaded?
- 25%
- 30%
- 33% (Correct answer)
- 40%
Correct answer: 33%
6 equal sectors each represent 100/6 ≈ 16.7%; two sectors = 2/6 ≈ 33%.
Question 6: A bar chart shows revenue growth rates: Year 1=5%, Year 2=8%, Year 3=−3%, Year 4=10%. In which year did revenue actually decrease?
- Year 1
- Year 2
- Year 3 (Correct answer)
- Year 4
Correct answer: Year 3
A negative growth rate in Year 3 (−3%) means revenue was lower than the previous year.
Question 7: A scatter plot shows data points clustered along a diagonal from bottom-left to top-right, with very little scatter. This indicates:
- Weak positive correlation
- Strong negative correlation
- Strong positive correlation (Correct answer)
- No correlation
Correct answer: Strong positive correlation
Points tightly clustered along an upward diagonal indicate a strong positive correlation between the variables.
