The following table shows the instruction type breakdown per processor of given applications executed in different numbers of processors.

Assume that each processor has a 2 GHz clock rate.

How much is the execution time of the program improved if the CPI of INT and FP instructions is reduced by 40% and the CPI of L/S and Branch is reduced by 30%?
