UGC-NET | UGC NET CS 2017 Jan – III | Question 48

A software company needs to develop a project that is estimated as 1000 function points and is planning to use JAVA as the programming language whose approximate lines of code per function point is accepted as 50. Considering a = 1.4 as multiplicative factor, b = 1.0 as exponential factor for the basic COCOMO effort equation and c = 3.0 as multiplicative factor, d = 0.33 as exponential factor for the basic COCOMO duration equation, approximately how long does the project take to complete?

(A)

11.2 months

(B)

12.2 months

(C)

13.2 months

(D)

10.2 months

Answer: (B)

Explanation:

In basic COCOMO we know that: 
E effort = a(KLOC)^b
According to given data i.e.

 a = 1.4 b = 1.0  total loc = 1000x50 = 50000 = 50 KLOC.
          E effort = 1.4(50)1
                   = 70
      Development time = c(E)d 
it is given that c = 3 and d = 0.33
So, Development time = 3(70)0.33
i.e.                 = 12.18 months.

So, option (B) is correct.
