Assume that $90\%$ of the time, a program can be cnhanced by a factor of $50.$ How much of the remaining time

must use an enhancement factor of $25$ to get an overall speedup of $40?$

A$.0\mathrm{.}14\%$

B$.0\mathrm{.}0014\%$

C$.0\mathrm{.}106\%$

$(6)9\mathrm{.}7\%$

E$.5\mathrm{.}9\%$

If we can nercase the clock ratc by $12\%$ then what is the specdup for a given program?

A$.12$

$($B$)1\mathrm{.}12$

C$.1\mathrm{.}2$

D$.0\mathrm{.}89$ ; new design is slower

$\frac{1\mathrm{.}12}{1}$

E $112$
