Consider a particular parallel program computation requires 200 sec when executed on a single processor. If 30% of this computation is inherently sequential (i.e. will not benefit from additional processors), then theoretically best possible elapsed times of this program running with 2 and 7 processors, respectively, are
1
100 sec and 75 sec
2
150 sec and 75 sec
3
130 sec and 80 sec
4
150 sec and 100 sec
