| Question 1 |
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 L2is 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?
| 2000 | |
| 6000 | |
| 3000 | |
| 5000 |
Question 1 Explanation:
Let LOC of L1=X, so LOC of L2=3X
→ (X/1,000)*70,000 + 10*1,00,000 = (3X/1,000)*90,000 + 10*40,000
→70X+1000000=270X+400000
→200X=600000
→X=3000
→ (X/1,000)*70,000 + 10*1,00,000 = (3X/1,000)*90,000 + 10*40,000
→70X+1000000=270X+400000
→200X=600000
→X=3000
Correct Answer: C
Question 1 Explanation:
Let LOC of L1=X, so LOC of L2=3X
→ (X/1,000)*70,000 + 10*1,00,000 = (3X/1,000)*90,000 + 10*40,000
→70X+1000000=270X+400000
→200X=600000
→X=3000
→ (X/1,000)*70,000 + 10*1,00,000 = (3X/1,000)*90,000 + 10*40,000
→70X+1000000=270X+400000
→200X=600000
→X=3000
