The GMAT exam seemed difficult until I found Dumpsforsure. Their updated practice questions gave me the edge I needed to succeed. I’m so glad I chose them.
Dumpforsure seems like fake/spam.

Risky approach but can see like this...

Apprentice are 75% of his speed
Trainees are 20% of his speed
Both together are 95% nearly as fast as him...
Now... The worker + 2 Pairs of apprentice and trainee.. thrice the rate means 1/3 time...means 1/3 of 300 minutes means 100 minutes... makes it 1 hour 40 mins.... C is the closest...

Food allergies account for more than thirty thousand emergency department visits each year. Often, victims of these episodes are completely unaware of their allergies until they experience a major reaction. Studies show that 90 percent of food allergy reactions are caused by only eight distinct foods. For this reason, individuals should sample a minuscule portion of each of these foods to determine whether a particular food allergy is present.

Which of the following must be studied in order to evaluate the recommendation made in the argument?

(A) The percentage of allergy victims who were not aware of the allergy before a major episode

(B) The percentage of the population that is at risk for allergic reactions

(C) Whether some of the eight foods are common ingredients used in cooking

(D) Whether an allergy to one type of food makes someone more likely to be allergic to other types of food

(E) Whether ingesting a very small amount of an allergen is sufficient to provoke an allergic reaction in a susceptible individual

CR 2

Studies show that impoverished families give away a larger percentage of their income in charitable donations than do wealthy families. As a result, fundraising consultants recommend that charities direct their marketing efforts toward individuals and families from lower socioeconomic classes in order to maximize the dollar value of incoming donations.

Which of the following best explains why the consultants' reasoning is flawed?

(A) Marketing efforts are only one way to solicit charitable donations.

(B) Not all impoverished families donate to charity.

(C) Some charitable marketing efforts are so expensive that the resulting donations fail to cover the costs of the marketing campaign.

(D) Percentage of income is not necessarily indicative of absolute dollar value.

(E) People are more likely to donate to the same causes to which their friends donate.

Seafood restaurants in Snare Island generally serve only fish caught in the waters around Snare Island since inhabitants are accustomed to the distinctive taste of Snare fish. Nevertheless, fishermen from Chinua, a nearby island, plan to sell Snare Island residents fish caught in Chinuan waters by selling at a lower price than that of Snare fish and marketing it as a low-fat alternative.

Which of the following, if true, casts most doubt on the viability of the plan by Chinua's fishermen to sell their fish in Snare Island?

(A) Many of the species of fish caught by Snare Island fishermen and Chinuan fishermen are closely related.

(B) Consumers in Snare Island eat fish in restaurants about as often as do consumers in Chinua.

(C) At times in the past, Snare Island fishermen have sold much of their catch to buyers in Chinua.

(D) The warmer climate in Chinua allows Chinuan fishermen to harvest fish more months of the year than can Snare Island fishermen.

(E) Most Snare Island residents are not concerned about their diet and believe that locally-caught fish are low-fat.

Which of the following most logically completes the argument below?

When malaria rates in a tropical country are high, drug companies reduce the cost of many kinds of anti-parasite medications. The reason is that drug companies want to take in as much money as possible in medication sales so that they can invest the money into research for more profitable drugs. Anti-parasite drug cost reductions are likely to achieve this objective since __________.

(A) when prices decrease, more companies enter the market with competing anti-parasite drugs

(B) drug companies that spend a smaller percentage of revenues on research are unable to take advantage of anti-parasite drug cost reductions for this reason

(C) many more people will purchase anti-parasite medications if the price is lower than if the price remained the same

(D) an increase in the number of anti-parasite drugs sold raises the likelihood that some species of parasite will mutate so that the drug is not effective against it

(E) resulting research is unlikely to result in a malaria vaccine
