UGC NET CSE | July 2018 | Part 2 | Question: 11

Question

 

Assume the following regarding the development of a software system P:

• Estimated lines of codes P : 33, 480 LOC
• Average productivity for P : 620 LOC per person -month
• Number of software developers : 6
• Average salary of a software developer : INR 50, 000 per month

If E, D and C are the estimated development effort (in person-month), estimated development time (in months), and estimated development cost (in INR Lac) respectively, then (E, D, C) = ______

• A. (48, 8, 24)
• B. (54, 9, 27)
• C. (60, 10, 30)
• D. (42, 7, 21)

Answer 1

option 2 is correct 

LOC in P =33480

Avg productivity=620 LOC per person month  , No of developers =6 , Avg salary 50,000 per month per person

E (development effort )=33480 /620 person months= 54 person months

D(development time) =54/6 (since 6 developers are there)= 9 months

C(development cost)   = 50000 x6x9 =27 lacs

Answer 2

Answer : (2). (54, 9, 27)

Reason :

We have given with Average Productivity for P = 620 LOC per person-month and we also have 6 Developers.

So  Single person can do 620 LOC
Therefore, 6 Developer can do  = 6 x 620 = 3720 LOC in a month
Now we need to calculate time T to complete the Project     

                 T = Estimated Line of Code / 6 Developers Line of Code per Month =     33480 / 3720 =  9

Now we need to calculate cost to complete the project in 9 months with given average salary of  ₹ 50,000 per month.

                                          Cost = 6 x 9 x 50000  = 27,00,000 (27 Lacs)
So Correct answer is option (2).

Answer 3

Option (2 ) 54, 9, 27

E = $\frac{Estimated LOC of P}{Avg Productivity of P}$

E  = 33480 / 620 

E = 54    there's only one 54 in answer i.e. Option (2 )

Answer 4

Answer is (54, 9, 27)

We have given with Average Productivity for P = 620 LOC per person-month and we also have 6 Developers.

So Single person can do 620 LOC
Therefore       6 Developer can do  = 6 x 620 = 3720 LOC in a month
Now we need to calculate time T to complete the Project      

                                          T =            Estimated Line of Code               =     33480     =  9

                                                6 Developers Line of Code per Month           3720

Now we need to calculate cost to complete the project in 9 months with given average salary of  ₹ 50,000 per month.

                                          Cost = 6 x 9 x 50000  = 27,00,000 (27 Lacs)

So Correct answer is option (2).
