Q1➡|NTA UGC NET November 2020 A company has a choice of two language L1 and L2 to develop a software for their client. Number of LOC required to develop an application in L2 is thrice the LOC in language L1. Also, software has to be maintained for the next 10 years. Various parameters for two languages are given below to decide which language should be preferred for development. PARAMETER L1 L2 Man-year needed for development LOC/1000 LOC/1000 Development cost Rs.70, 000 Rs.90, 000 Cost of Maintenance per year Rs.1, 00,000 Rs.40, 000 Total cost of the project includes the cost of development and maintenance. What is the LOC for L1for which cost of developing the software with both languages must be the same?
i ➥ 2000
ii ➥ 5000
iii➥ 3000
iv ➥ 6000
Show Answer With Best Explanation
Answer: iii Solution: It is given that number of LOC required to develop an application in L2 is thrice the LOC in language L1. Suppose, Number of LOC required in L1 = x so, Number of LOC required in L2 = 3x Cost of developing the software = (Number of LOC / Man-year needed for development) * Development cost + Maintenance Time *Cost of Maintenance per year & condition is that cost of developing the software with both languages must be the same. => Cost of developing the software in L1 = Cost of developing the software in L2 => (x /1000)* 70,000 + 101,00,000 = (3x /1000) 90,000 + 10*40,000 => 70x + 10,00,000 = 270x + 4,00,000 => 200x = 6,00,000 => x = 3000

Q4➡| NTA UGC NET November 2020 A Software project was estimated at 864 Function Points. A six person team will be assigned to a project consisting of a requirement gathering person, one designer, two programmers and two testers. The salary of the designer is ₹70,000 per month, requirement gatherer is ₹50,000 per month, programmer is ₹60,000 per month and a tester is ₹60,000 per month.

Show Answer With Best Explanation
Answer – B Explanation– Given that , –> Total Function points = 864 FP –> Team = 6 person –> Average Function points= 12 FP per person month. –> projected cost =? we have to first calculate in how many month a team will completed their task ,then calculate what is the cost of the project? In a 6 member team, –> one person is Requirement gatherer –> one person is Designer –> two person is Programmers –> two person is Testers
Q5➡|NTA UGC NET November 2020 Modifying the software by restructuring is called.
i ➥ Adaptive maintenance
ii ➥ Corrective maintenance
iii ➥ Perfective maintenance
iv➥ Preventive maintenance
Show Answer With Best Explanation
Answer: iii Explanation: There are four types of software maintenance: • Corrective Software Maintenance • Adaptive Software Maintenance • Perfective Software Maintenance • Preventive Software Maintenance Corrective Software Maintenance: Corrective maintenance deals with the repair of faults or defects found in day-today system functions. A defect can result due to errors in software design, logic and coding.
Adaptive Software Maintenance: Adaptive maintenance is concerned with the change in the software that takes place to make the software adaptable to new environment such as to run the software on a new operating system.
Perfective Software Maintenance: Perfective maintenance is concerned with the change in the software that occurs while adding new functionalities in the software.Modifying the software by restructuring is called preventive software maintenance.
Preventive Software Maintenance: Preventive maintenance involves implementing changes to prevent the occurrence of errors.
