The number lines of code (LOC) developed using L2 is estimated to be twice of the LOC developed with L1. The product will have to be maintained for five years. Various parameters for the company are given in the table below. Parameter Language L1 Language L2 Man years needed for development LOC/10000 LOC/10000 Development Cost per man year र 10, 00, 000 र 7, 50, 000 Maintenance Time 5 years 5 years Cost of maintenance per year र 1,00,000 र 50, 000 Total cost of the project includes cost of development and maintenance. What is the LOC for L1 for which of the cost of the project using L1 is equal to the cost of the project using L2? 4000 5000 4333 4667 IS&Software Engineering gatecse-2011 is&software-engineering project-cost normal isro2016 + – go_editor asked Sep 29, 2014 • retagged Nov 13, 2017 by Arjun go_editor 7.7k views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
Best answer 14 votes 14 votes Answer: B Let L1 = x and L2 = 2x Then, (x*1000000)/10000 + 5*100000 = (2x*750000)/10000 + 5*50000 => x*100 + 5*100000 = 2x*75 + 5*50000 => 50x = 250000 => x = 5000 Rajarshi Sarkar answered Jun 2, 2015 Rajarshi Sarkar comment Share Follow See all 2 Comments See all 2 2 Comments reply habedo007 commented Nov 26, 2017 reply Follow Share In which section of software engineering can I find this formula? 0 votes 0 votes Sandeep652025 commented Feb 25, 2022 reply Follow Share Cocomo Model 0 votes 0 votes Please log in or register to add a comment.
