Question 1

A table shows exports in billions: Country A exported $4.2B, Country B $3.8B, Country C $5.1B, Country D $2.9B. What fraction of total exports does Country C represent (approximately)?

Accepted Answer

34%

Answer

Total = 4.2 + 3.8 + 5.1 + 2.9 = 16.0; Country C share = 5.1 / 16.0 × 100 ≈ 31.9% ≈ 32%.

Question 2

A histogram shows test scores grouped in bands: 40–49 (5 students), 50–59 (12 students), 60–69 (20 students), 70–79 (8 students), 80–89 (5 students). What percentage of students scored 60 or above?

Accepted Answer

66%

Answer

Students scoring 60+: 20 + 8 + 5 = 33; total = 50; 33/50 × 100 = 66%.

Question 3

A two-way table shows survey results: 60 men and 40 women prefer Brand A; 30 men and 70 women prefer Brand B. What percentage of all respondents prefer Brand A?

Accepted Answer

50%

Answer

Brand A total = 60 + 40 = 100; total respondents = 60 + 40 + 30 + 70 = 200; 100/200 = 50%.

Question 4

A graph shows that a city's population grew from 250,000 in 2010 to 310,000 in 2020. At the same annual growth rate, what will the population be in approximately 2025?

Accepted Answer

342,000

Answer

Growth over 10 years = 60,000; annual growth = 6,000; 2025 population ≈ 310,000 + (5 × 6,000) = 340,000 (linear approximation gives 340,000, but compound gives ~342,000).

Question 5

A stacked bar chart shows total project hours: Planning 15%, Execution 55%, Review 20%, Reporting 10%. If the project took 400 hours total, how many hours were spent on Review and Reporting combined?

Accepted Answer

120

Answer

Review + Reporting = 20% + 10% = 30%; 30% of 400 = 120 hours.
