Kooclaka is a full-line vending business, which uses vending machines to sell cans or bottles of soft drinks and individual packages of snacks. When the management of Kooclaka considered whether to fill vending machines in hospitals with 330ml or 500ml cans or bottles, it decided to sell only 500ml bottles, because patients do not leave their beds very often, thus they prefer a larger, reusable bottle.

Which of the following if true weakens the argument above?

A. All of Kooclka's products are manufactured by the same manufacturer.

B. The revenues from selling 500ml bottles are 5% less than for 500ml cans.

C. Most of Kooclka's competitors sell only 500ml bottles in hospitals.

D. More 330ml bottles then 500 ml bottles can be put together in a vending machine.

E. The average number of visitors is 2.3 per hospital patient.

When analysing the argument
Main Conclusion: thus they prefer a larger, reusable bottle.
Primary premise: because patients do not leave their beds very often.

How can we weaken the conclusion?
i) by destroying the premise
ii) by adding a premise to weaken the conclusion

Answer option B does the latter. By adding additional premise the author says that the company uses bottles instead of cans, because of revenue purposes(less revenue doesnt mean less profit) and not because patients do not leave their beds often(as mentioned in the argument).
While option E says that for 10 patient there are 23 visitors. But it doesnt mention anything about whether the visitors buy bottles for patients.

Correct me if i am wrong

Expert reply will be very much appreciated GMATNinja souvik101990 hazelnut GMATNinjaTwo

Which of the following, if true, most seriously weakens the argument above?

I am confused with the conclusion of the sentence... lets break the sentence into 2 parts , Part A: Mgmt decided to sell only 500 bottles Part B: Patients do not leave their beds and prefer large reusable bottle

Part A, hence part B or Part B hence part A, thus Part A sounds to be the conclusion.

Conclusion: Mgmt decided to sell only 500 bottles

Arg: Patients prefer large reusable bottles and do not leave bed ----->mgmt decided to launch 500 bottles, kind of a cause and effect relation.
Weakener: Effect happened but some other reason caused this decision, which can be told from Option C. It is because competitors were using 500 bottle, mgmt decided to sell 500 bottles

Please correct me if i am wrong

A tricky question;
Decision taken by Companies can be weaken by showing any additional evidence impacting their revenue, IMO.
So Only B does the same.

Kooclaka has 300mL cans, 300mL bottles, 500mL cans and 500 mL bottles.
Hospital patients stay in bed always, so they prefer large and reusable containers.
Either 500mL cans or 500mL bottles.
Kooclaka decides to go with 500mL bottles.

To weaken it, we need to show that 500mL cans are better. How?

A. All Kooclaka’s products are manufactured by the same manufacturer.

So, Nobody cares. Irrelevant.

B. The revenues from selling 500ml bottles are 5% less than for 500ml cans.

Shows that obviously cans are more profitable!! Done!

C. Kooclaka’s competitors sell only 500ml bottles in hospitals.

Good for you guys. But, so what? Irrelevant.

D. More 330ml bottles than 500ml bottles can be put in a vending machine.

That's good. But it does not compare the revenues. Maybe 300mL bottles are way too cheap, and moreover patients dont even prefer them. Loss of revenue, either way.

E. The average number of visitors is 2.3 per hospital patient.

That means the visitors may prefer 300mL cans. But, we still dont know how that affects the revenue stream. Maybe they may also like 500mL cans? Not entirely sure.

So, Answer is Option B.

Between B, D, E.

E -> This can be the choice if we know the preference of the visitors, but we don't.
D -> Same, the trick here is that, more 330 ML bottles are not preferred by patients. So, It may not lead to increase in revenue. It can, but given the same circumstance it might not. We require assumptions here.
B --> Correct, Unfortunately I missed the "bottles and cans" in the text and chose D. B makes more sense if we read carefully.

Tx.
