A Company has a choice of two languages L 1and L 2to develop a software for their client. Number of LOC required to develop an application in L 2, is thrice the LOC in language L 1. Also, software has to be maintained for next 10 years. Various parameters for two languages. are given below to decide which language should be preferred for development. PARAMETER L 1 L 2 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 project include cost of development and maintenance. What is the LOC for L 1 for which cost of developing the software with both languages must be same ?
3000
Let x be the LOC in L1, so L2 requires 3x LOC.
Step 1 — Total costs:
\(C_1=70x+10(100000),\quad C_2=270x+10(40000).\)
Step 2 — Equate costs:
\(70x+1000000=270x+400000\Rightarrow x=\frac{600000}{200}=3000.\)
