Critical Reasoning

Which of the following logical inferences can be made given the situation below?

Most businesses in India use computer technology. A leading computer manufacturer with 1 million customers estimates that the only way it can be successful is if it increases its customer base to include one half of all businesses in India that currently use computer technology.


(A) The computer manufacturer must sell computers to at least one quarter of all Indian businesses to be successful.

(B) There are over 10 million businesses in India that do not use computer technology.

(C) No more than three quarters of businesses in India currently use computer technology.

(D) There are at least 8 million businesses in India overall.

(E) There are at least 8 million businesses in India that use computer technology.

A

Humm IMO : E.. not getting any logic to infer A.

Sorry

Often when you see CRs with numbers you can solve them by approaching them as a math problem rather than a verbal problem.

Lets assume that there are 5 million businesses in India that use computers. To be successful the company must include half of those customers meaning at least 2.5 million.

What does A state? Must sell computers to at least one quarter of all Indian businesses to be successful. Lets put that into numbers.

We know from the passage that "most" businesses in India use computers. Most means at least 50%. So going back to our example that means 5 million use computers and 5 million do not. That means there are a total of 10 million busineeses. 25% of 10 million is 2.5 million, or the minimum number the company must have to be a success.

You can use any number you want as a starting point and you will see that at least 25% must be customers.

For E to be correct the passage needs to give us actual numbers, which they do not. All we know is that a manufacturer has 1 million customers. Even if we assume that those are all in India all that tells us is that there are more than 2 million computer using businesses in India. Thats it. It never reached 8 million or or 10 million.

No problem. First lets go back to the passage and get the information from there.

We are told that this computer manufacturer has 1 million customers. They need to increase thst to be at least half of the businesses that use computers in India. Because they need to increase it it means that 1 million is less than half of the businesses using computers.

Everything given in the passage is percentages except the 1 million number. So that is the base number to use to determine the musts. So here is what is fact:

Company- has 1 million customers
India- Greater than 2 million computer using businesses.

So E tells us that at least 8 million businesses use computers. That could be correct, but it doesnt have to be. All we know for fact is that there are more than 2 million businesses in India that use computers. It could be 2,000,001 or it could be 100,000,000. We cant tell the exact number. All we know is there has to be more than 2 million to fit the criteria that 1 million is less than half.
