Thank you

12. A program is 30% add instructions. We speed up add by 50%. If the program previously took 10 seconds to run, how long will it take to run now?

Total time previously= 10seconds

Add instructions time previously= 30%=0.3*10=3 seconds

Currently speedup of add instructions=50%

So current time for add instructions execution= 3seconds - 50% of 3seconds=3-1.5=1.5seconds

Current total time for execution of all instructions= previous total time - 1.5seconds=10-1.5=8.5 seconds
