The number of function points of a proposed system is calculated as 500. Suppose that the system is planned to be developed in Java and the LOC/FP ratio of Java is 50. Estimate the effort (E) required to complete the project using the effort formula of basic COCOMO given below :
E = a(KLOC)b
Assume that the values of a and b are 2.5 and 1.0 respectively.
Answer: C. 62.5 person months — Solution: Compute LOC from function points, convert to KLOC, then apply the basic COCOMO formula. Compute total lines of code (LOC): 500 function points × 50…
- A.

Show answer & explanation
Correct answer: C
Solution: Compute LOC from function points, convert to KLOC, then apply the basic COCOMO formula.
Compute total lines of code (LOC): 500 function points × 50 LOC/function point = 25,000 LOC.
Convert LOC to KLOC: 25,000 LOC ÷ 1,000 = 25 KLOC.
Apply the basic COCOMO effort formula E = a × (KLOC)^b with a = 2.5 and b = 1.0: E = 2.5 × (25)^1.0 = 2.5 × 25 = 62.5 person-months.
Final answer: 62.5 person-months.
