In a particular program, it is found that 1% of the code accounts for 50% of the execution time. To code the program in FORTRAN, it takes 100 man-days. Coding in assembly language is 10 times harder than coding in FORTRAN, but runs 5 times faster. Converting (rewriting) an existing FORTRAN program to an assembly language program is 4 times harder than coding in FORTRAN.

If a project team needs 13 days to completely write the program in FORTRAN and rewriting (converting) the 1% code to assembly language, then the team consists of

Show answer & explanation

Correct answer: C. 8 Programmers

Explanation

Writing the entire program in FORTRAN takes 100 man-days (given). The 1% of code that is later converted to assembly would take 1% of 100 = 1 man-day in FORTRAN, and converting existing FORTRAN code to assembly is 4 times as hard as coding it in FORTRAN, so the conversion costs 4 x 1 = 4 man-days. Total effort = 100 + 4 = 104 man-days, and completing this in 13 calendar days requires a team of 104 / 13 = 8 Programmers.
