Computer A has an overall CPI of $1\mathrm{.}3$ and can be run at a clock rate of $600Mhz.$

Computer B has an overall CPI of $2\mathrm{.}5$ and can be run at a clock rate of $750Mhz.$

When a particular program is compiled for computer A it has exactly $100,000$ instructions.

How many instructions would the program needs to have when compiled for Computer B$,$ in order for the two computers to have exactly the same execution time for this program?
