Passage

Cloud computing is fast emerging as the new solution to all your storage and computing needs. It is becoming

more and more appealing because of its scalability and efficient usage of resources. Each time new

technological advances have been made in the past, organisations have taken advantage of them, and the

transition to cloud computing has followed this pattern in turn.

Until the advent of cloud computing, organisations used their own resources to store and deploy content. There

were limitations to this method though because eventually, the resources would get exhausted and the

company would have to invest in additional storage solutions. Alternatively they would have to delete or archive

old content to make way for new. Either way, this was not the best solution because it required time and money

to implement these methods.

Cloud computing is an attractive alternative to storage on internal resources because it can be scaled

dynamically and also because it makes efficient use of available resources. Organisations now not only store

their data on the cloud, but store software applications too. Users connect to the c oud and use it and

applications freely.

In cloud computing resources can either be externally owned, examples of which are public storage facilities

provided by Google and Amazon or internally owned known as ‘private clouds’. Public clouds provide access to

external users and charge them on a pay-as-you-use basis.

There are several advantages to storing data and software on the cloud. The first and primary advantage is

reduction in cost. On the cloud, you have the option of using only as much data storage as you need. This

means that you do not need to invest in extra resources if it would be unnecessary to do so.

On the cloud you can also get instant software updates because the changes need to be made on the software

that is being hosted on the cloud. Consequently, users do not need to make any changes to their own

computers. This saves a lot of time that would normally be taken up in downloads and uploads.

Finally, a very important advantage is data security. As the cloud is used exclusively for data and software

storage data security always remains of paramount concern. In addition, there are backups stored in various

locations and this ensures that your data is never compromised either by hackers or through other means.

Which of the following statements does not support the conclusion in the passage?

If x is a positive integer such that,  

then what is the value of x?

TT Phones is a leading global mobile manufacturing company. In the year 2014-2015, Country X registered a

sales growth of 128% of TT Phones over the previous year, whereas TT Phones’ largest market Country Y

registered a growth of 34%. The budget allocated for sales and promotions in Country X is two times that

allocated for Country Y. In spite of this, the actual numbers of mobile phone units expected to be sold in

Country X and Y are 1.83 million and 4.65 million respectively in the year 2015-16.

Which of the following can be inferred from the above statements?

The probability that Event X happens in one trial of an experiment is 0.19. Three independent trials of the

experiment are performed. What is the probability that Event X happens at least once?
