Consider two different implementations, P$1$ and P$2,$ of the same instruction set architecture. The instructions can be divided into four classes according to their CPI $($classes A$,$ B$,$ C$,$ and D$).$ P$1$ with a clock rate of $2\mathrm{.}5$ GHz and CPIs of $1,2,3,$ and $4$ respectively, and P$2$ with a clock rate of $3$ GHz and CPIs of $2,2,2,$ and $2$ respectively. Given a program with an instruction count of $1\mathrm{.}0$E$9($this is the scientific notation for writing $1*109)$ instructions, is divided into classes as follows: $20\%$ class A$,10\%$ class B$,40\%$ class C$,$ and $30\%$ class D
