Assume that a programme consisting of Floating point (FP), Load/Store (L/S) and Integer arithmetic (INT) instructions takes 1000sec to finish if executed on processor P1. The Floating point (FP) instructions take 30% of the total execution time, whereas the Load/Store (L/S) instructions take 45% of the total execution time.

(a) Calculate how much time (in seconds) is spent executing INT instructions? [2 points]

(b) Calculate by how much the total time will change (increase/reduce) if the time spent on executing

FP operations is reduced by 40% and the time for INT instructions is increased by 20%? [5 points]
