It would be E right. r can be anything. r can be π. In that case even if s is 8,it would still not be a terminating decimal. So both statements are not sufficient

i understand this point though, r is pie then it would be non terninating

because they haven’t mentioned that r is an integer

Pure algebraic questions are no longer a part of the DS syllabus of the GMAT.

DS questions in GMAT Focus encompass various types of word problems, such as:

  • Word Problems
  • Work Problems
  • Distance Problems
  • Mixture Problems
  • Percent and Interest Problems
  • Overlapping Sets Problems
  • Statistics Problems
  • Combination and Probability Problems

While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won’t encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."

Check GMAT Syllabus for Focus Edition

You can also visit the Data Sufficiency forum and filter questions by OG 2024-2025, GMAT Prep (Focus), and Data Insights Review 2024-2025 sources to see the types of questions currently tested on the GMAT.

So, you can ignore this question.

Hope it helps.­

Critical Reasoning Butler: February 2025
February 19CR 1CR 2

_____________________________
CR 1

When it comes to purity standards in the food industry, demanding the most exacting results that the best hygiene practices can achieve is unwise. Although contemporary hygiene practices can isolate and eliminate the most minute amounts of impurities, doing so is exorbitantly expensive, with respect to the improvement achieved. Thus, it would be more reliable to set standards by accounting for all current and future risks involved than by demanding the best hygiene practices

The argument given concerning the better way to set standards assumes that

A. at present, the food industry meets the standards established by public health authorities
B. the only impurities worth gauging are introduced by the food industry
C. all of the relevant risks posed by allowing different levels of impurities can be accounted for effectively
D. preventing vast quantities of impurities from entering the food supply chain is not expensive
E. minuscule amounts of some impurities can be toxic

_____________________________
CR 2

Non-capitalist states appear to suffer economic collapse much sooner than do capitalist states. Historians theorize that it is interventionism and destabilizing influences exercised by capitalist states that lead to non-capitalist states suffering economic collapse faster than capitalist states do. This theory is hard to verify directly, as it is difficult to pinpoint with any significant accuracy what punitive practices have been undertaken by capitalist states against non-capitalist ones. A detailed study of Cuba, a non-capitalist state, however, demonstrates that much of the economic difficulty experienced by the nation arises from sanctions and trade embargoes placed by the USA, a capitalist state. This indicates that the historians’ theory has a firm basis in reality.

In the argument given, the two boldfaced portions play which of the following roles?

A. The first describes a position opposed by the argument; the second presents evidence that undermines support for the opposed position.
B. The first describes a position opposed by the argument; the second states the argument’s main conclusion.
C. The first presents an explanatory hypothesis; the second states the argument’s main conclusion.
D. The first presents an explanatory hypothesis; the second presents evidence that supports alternative explanation.
E. The first presents an explanatory hypothesis; the second presents evidence that tends to support this hypothesis.
