This one sits right at the intersection of Data Sufficiency and Data Insights table-reading — exactly the kind of hybrid question the GMAT Focus Edition loves to test.
Key concept being tested: Range in grouped data, and what individual data points tell us about that range
The table (grouped frequency distribution):
$20,000–$29,999 → 4 stores
$30,000–$39,999 → 14 stores
$40,000–$49,999 → 27 stores
$50,000–$59,999 → 9 stores
$60,000–$69,999 → 2 stores
Question: Is the range of revenue greater than $32,000?
Range = (highest value) − (lowest value). The table shows intervals, not exact revenues. So we need the actual maximum and minimum store values.
Statement (1): The highest-earning store generated $62,000 in revenue.
Now we know the exact maximum: $62,000. The lowest interval is $20,000–$29,999, so the minimum is somewhere between $20,000 and $29,999.
- If minimum = $29,999 → Range = $62,000 − $29,999 = $32,001 > $32,000 ✓
- If minimum = $20,000 → Range = $42,000 > $32,000 ✓
The minimum is at most $29,999, so the range is at minimum $62,000 − $29,999 = $32,001. Always greater than $32,000.
Statement (1) is SUFFICIENT.
Statement (2): The lowest-earning store generated $25,000 in revenue.
Minimum = $25,000. The maximum is somewhere in $60,000–$69,999.
- If maximum = $60,000 → Range = $35,000 > $32,000 ✓
- If maximum = $69,999 → Range = $44,999 > $32,000 ✓
The maximum is at least $60,000, so the minimum range is $60,000 − $25,000 = $35,000 > $32,000. Always yes.
Statement (2) is also SUFFICIENT.
Answer: D (Each statement alone is sufficient)
Common trap: Students assume grouped data means you can't pin down exact values. But when a statement gives you a specific individual data point — the highest or lowest store — that IS an exact value. The trap is forgetting to check whether the other extreme (still stuck in an interval) creates any ambiguity. Here, both extremes resolve cleanly.
Takeaway: In grouped frequency table DS questions, the key question is always: do I know enough about the actual maximum and minimum — not just the intervals they fall into?

Explanation:
We need to find whether the range of the revenue is greater than 32,000.
Statement (1)
Highest revenue = 62,000.
Maximum possible range = Highest revenue – Lowest possible revenue = 62,000 – 20,000 = 42,000 > 32,000.
It is possible to determine with certainty that the range of the revenue is greater than 32,000. Hence, Statement (1) is sufficient.
Statement (2)
Lowest revenue = 25,000.
Maximum possible range = Highest possible revenue – Lowest revenue = 69,999 – 25,000 = 44,999 > 32,000.
It is possible to determine with certainty that the range of the revenue is greater than 32,000. Hence, Statement (2) is sufficient.
D is the correct answer choice.
