UPSC CSE Prelims 2024

A Question is given followed by two Statements I and II. Consider the Question and the Statements.

Question: What is the time required to download the software?

  1. Statement-I: The size of the software is 12 megabytes.
  2. Statement-II: The transfer rate is 2.4 kilobytes per second.

Which one of the following is correct in respect of the above Question and the Statements?

EXPLANATION

Correct Option (3)

To determine the time required for software download, two fundamental pieces of information are essential: the total size of the software and the rate at which data is transferred. Statement-I provides the size of the software (12 megabytes), and Statement-II provides the transfer rate (2.4 kilobytes per second). When both statements are considered concurrently, all the necessary data becomes available to calculate the download time using the relationship: Time = Size / Rate of transfer. Therefore, the question can be definitively answered by utilizing both statements together.

Incorrect Options:

  • The Question cannot be answered using Statement-I alone. While it specifies the software size, it lacks information regarding the data transfer rate. Without the rate, the duration of the download cannot be computed.
  • Similarly, the Question cannot be answered using Statement-II alone. It provides only the transfer rate but does not specify the total size of the software. Both parameters are indispensable for determining the download time.
  • Since both statements together furnish all the requisite information (software size and transfer rate), the question is indeed answerable. Consequently, the assertion that the question cannot be answered even by using both statements together is incorrect.
