Introduction
Harish's transaction with two computers involves calculating the profit and loss percentages from the sales. Let's break down the costs and sales to determine his overall financial outcome.
Cost Price of Computers
- First Computer: Rs 20,000
- Second Computer: Rs 18,000
Total Cost Price
- Total Cost = Cost of First Computer + Cost of Second Computer
- Total Cost = Rs 20,000 + Rs 18,000 = Rs 38,000
Profit on First Computer
- Selling Price of First Computer = Cost Price + Profit
- Profit = 15% of Rs 20,000 = (15/100) * 20,000 = Rs 3,000
- Selling Price = Rs 20,000 + Rs 3,000 = Rs 23,000
Loss on Second Computer
- Selling Price of Second Computer = Cost Price - Loss
- Loss = 10% of Rs 18,000 = (10/100) * 18,000 = Rs 1,800
- Selling Price = Rs 18,000 - Rs 1,800 = Rs 16,200
Total Selling Price
- Total Selling Price = Selling Price of First Computer + Selling Price of Second Computer
- Total Selling Price = Rs 23,000 + Rs 16,200 = Rs 39,200
Overall Profit Calculation
- Overall Profit = Total Selling Price - Total Cost Price
- Overall Profit = Rs 39,200 - Rs 38,000 = Rs 1,200
Profit Percentage
- Profit Percentage = (Overall Profit / Total Cost Price) * 100
- Profit Percentage = (1,200 / 38,000) * 100 ≈ 3.16%
Conclusion
Harish achieved an overall profit of approximately 3.16% from the sale of the two computers.

Similar UPSC Doubts

PassageOver the years, the rise in technological innovations has corresponded with the rise in the computational capabilities of computers. First-generation computers had programs that were implemented by humans. However, the rise of computation has led to the development of algorithms - essentially a set of instructions to perform a calculation or solve a problem that can be implemented by a computer, and key to all Artificial Intelligence (AI) systems. The rise in algorithmic abilities brings us to the present-day scenario, where an AI system can interpret a set of instructions and is capable of deciphering the required output function it needs to perform. These algorithms are trained on massive datasets, i.e., training datasets, which provide it with a certain amount of input information and output information allowing it to recognize the tasks required to be performed to generate an output based on future real-world inputs. However, its ability to self-implement instructions and carry out these functions based on its training presents us with unique ethical considerations applicable to the use of AI systems in various capacities.Which one of the following statements best reflects the critical message conveyed by the passage given above?

Read the information given below carefully and answer the following question.The internet has become the integral part of today’s generation. Internet has touched every aspect of life. With the growing use of the internet by people, protecting important information has become a necessity. A computer that is not having appropriate security controls can be infected with malicious logic and thus any type of information can be accessed in moments. Hacking of important data, network outages, computer viruses and other cyber related threats affect our lives that range from minor inconvenience to serious incidents. Cyber threats can be caused due to negligence and vulnerabilities, or unintentional accidents. The main objectives of such type of system attackers or hackers are to steal confidential information, to make illegal monetarytransactions, to destroy or to change data and the like. System attackers usually use malicious logic or virus to gain unauthorized access to a computer. Opening email attachments that carry the virus, clicking malicious links or websites or unintentionally downloading a dangerous program are common ways through which a computer can be infected and data can be stolen. As the number of data networks, digital applications, as well as internet and mobile users are growing, so do the chances of cyber exploitation and cybercrimes. If accounts are not properly secured, it makes easier for hackers or unauthorized users to spread viruses or social engineered attacks that are designed to steal data and even money.Such types of issues highlight the need for cyber security as an essential approach in protecting and preventing data from being used inappropriately. In simple language, Cyber Security or Information technology security means protecting data, networks, programs and other information from unauthorized or unintended access, destruction or change. It encompasses all the mechanisms and processes that protect digital equipment, information and records from illegal or unintended access, manipulation or destruction. In today’s dynamic environment, cyber security has become vital for individuals and families, as well as organizations that collect and store a wide range of confidential data on computers and transmit that to other computers across different networks.Social networking sites have become the mostpopular medium for sharing information and connecting with other people. But these sites have created varied opportunities for cybercrimes, compromised personal identities and information leakage. Therefore, it is important for individuals to understand how to protect against cyber threats, and must also comprehend the difference between virtual and real world. One should learn how to protect computers and personal information from being hacked and should engage in appropriate online behaviour in order to eliminate changes of cyber threats and thereby creating a safer online environment.Q.According to this passage, how the virus gets into the computers?
