Answer = B 
Explanation: Let the first case takes 100 units of time to execute. Second case will take 99 +(1/5) units of time. As the 1% coding in assembly language will take 1/5 units of time. Hence the required percentage = 0.8*100/100 = 0.8.
10) If 99% of the program is written in FORTRAN and the remaining 1% in assembly language the percentage increase in the execution time, compared to writing the 1% in assembly language is?
a.    0.9
b.    0.1
c.     1
d.    0

Answer = D
Explanation: In both cases the final program will have the same 99% of code in FORTRAN and the remaining 1% in assembly language. Hence the execution time will remain same.
