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.

Q11. The entire program is written in FORTRAN. The percentage decrease in the execution time, resulting from rewriting the 1% of code (that accounts for 50% of execution time) into assembly language, is
