GMAT Data Insights: Integrated Reasoning Mixed Practice

Question 1

A table shows monthly sales ($000s) for Product A and Product B over 6 months:
Month 1: A=50, B=30
Month 2: A=55, B=35
Month 3: A=48, B=40
Month 4: A=60, B=38
Month 5: A=65, B=42
Month 6: A=70, B=45

Which of the following statements can be inferred from the data?

Accepted Answer

Product A showed a general upward trend over the 6-month period

Answer

Product A's values are: 50, 55, 48, 60, 65, 70 — showing a general upward trend despite a dip in Month 3. B is consistently lower than A. The two have different totals. B only declined from Month 4 to 5 — actually B went 30,35,40,38,42,45 (dip at Month 4).

Question 2

A two-part analysis problem provides: Company X's revenue grew by 20% in Year 1 and declined by 15% in Year 2. Company Y's revenue grew by 10% in both years. If both companies started with $1 million in revenue, which company had higher revenue after Year 2, and by how much?

Accepted Answer

Company Y by $10,000

Answer

X: 1M × 1.20 × 0.85 = $1.02M. Y: 1M × 1.10 × 1.10 = $1.21M. Y − X = 0.19M. None of these match exactly — but the closest provided answer showing Y leads is B.

Question 3

A graphic shows that a city's population grew from 500,000 in 2010 to 650,000 in 2020. Which of the following represents the approximate percent increase?

Accepted Answer

30%

Answer

% increase = (650,000 − 500,000)/500,000 × 100 = 150,000/500,000 × 100 = 30%.

Question 4

Multi-source data: Source 1 states that 60% of employees prefer remote work. Source 2 reports that productivity scores are 8% higher for in-office workers. Which conclusion is best supported by combining both sources?

Accepted Answer

Most employees prefer remote work even though in-office work shows a modest productivity advantage

Answer

Source 1 shows majority preference for remote. Source 2 shows a productivity edge for in-office. The most defensible combined conclusion acknowledges both facts without dismissing either.

Question 5

A table shows quarterly profit margins (%) for three divisions:

Q1: Div A=15%, Div B=20%, Div C=10%
Q2: Div A=18%, Div B=17%, Div C=14%
Q3: Div A=22%, Div B=15%, Div C=18%
Q4: Div A=20%, Div B=12%, Div C=22%

Which division showed a consistent downward trend in profit margin?

Accepted Answer

Division B

Answer

Division B: 20% → 17% → 15% → 12% — each quarter lower than the last. This is a consistent decline.
