1) False, since highest range is in 1980
2) False, since Serbia is having highest BP for 4 times
3) True, since 5/6 nations have BP<125 in 2000, so >50%

Official Explanation

Statement 1: False.   The range for a year is defined as the highest value minus the lowest value shown for that year. Rather than calculate the ranges for every year provided, use estimation to see if you can find any year with a greater range than 1992.

First sort by 1992. Notice that the minimum is 119.87 and the maximum is 137.48. If you can find a year that has a lower minimum and a higher maximum, that year would have a larger range and the statement would be false.

Sort by 1980. The minimum in this year was 118.65 (lower than in 1992) while the maximum in this year was 143.12 (greater than in 1992). Since the range in 1980 is greater than in 1992, 1992 cannot have the greatest range. The statement is False.

Note: if 1980 had not had a greater range, you would have next checked 1984 and so on.

Statement 2: False.   Sort each column independently, noting the country with the highest blood pressure for each year. The results are:

1980: Finland
1984: Finland
1988: Serbia
1992: Serbia
1996: Serbia
2000: Serbia

The nation that most frequently ranked highest in blood pressure was Serbia not Finland; this statement is False.

Note that if the sorting is performed chronologically, as shown above, then you could stop after checking 1996. At this point, Serbia was already the highest in 3 of the years, whereas Finland was the highest in only 2 of the years, so at best Finland could only tie with Serbia (if Finland were highest in 2000).

Statement 3: True.   First, find the countries with mean blood pressure below 125 mmHg in 1980. Sort by 1980. Six countries fix the requirement: Papua New Guinea, Cambodia, India, Thailand, Vietnam, and Nepal. Next, find how many of these countries had a mean blood pressure below 125 mmHg in 2000. Rather than sort by 2000, leave the table as it is and scan over to the 2000 column; if you find 3 (at least half), then you can stop.

Papua New Guinea, Cambodia, and Thailand are all still below 125 mmHg, so at least half of the countries do still fit the required statistic. This statement is True.

The first statement says: "male  systolic  blood pressure", but nowhere in the question it is specified that the blood pressures are systolic -- In such cases should we usually assume that the data given is what is being asked -- like we are assuming here?

Gmat860sanskar · Answer

Arushi,  Good observation. The values are above 110, so it’s reasonable to treat them as systolic blood pressure. However, for the GMAT, you don’t need to rely on technical knowledge like this. Just focus on the numbers given in the table and compare them directly to answer the question

egmat · Answer

Hi arushi118,

Great question! This is a  common concern  on GMAT  Table Analysis  questions.

The short answer:  Yes, on the GMAT you should work with the data you are given. The table provides exactly one set of blood pressure values per country per year. When a statement references 'male systolic blood pressure,' and the table only has one column of blood pressure data for each year, you should treat that data as the relevant data to evaluate the statement. The GMAT is not expecting you to have medical knowledge or to question whether the data is systolic vs. diastolic.

Think of it this way:  the table is titled 'Average Adult Male Blood Pressure' and provides values like  118.65  to  143.12  mmHg. These values are squarely in the  systolic blood pressure  range (normal systolic is around  120  mmHg, while diastolic is around  80  mmHg). So the data is consistent with being systolic readings.

But even if you didn't know that medical fact, the  GMAT principle is straightforward: if the question asks about blood pressure and the table gives you blood pressure numbers, use those numbers.   Don't overthink whether the table should have specified 'systolic'  — the test makers expect you to match the statement to the available data and verify it.

So for S1,  you would simply compute the  range  (max minus min across countries) for each year and check whether  1992  had the greatest range. It turns out  1980  had the greatest range ( 143.12  -  118.65  =  24.47 ), making S1  False .

Bottom line:  On the GMAT, the data in the table IS what the question is asking about.  Don't second-guess the data  — just use it.

Answer: False, False, True

True	False
		For the nations given, the range in male systolic blood pressure was greatest in 1992.
		Of the countries listed, no nation ranked highest in adult male blood pressure more frequently than did Finland.
		Of the nations listed with a 1980 blood pressure below 125 mmHg, at least half still remained below 125 mmHg in 2000.
