a) By how much is the total execution time changed if the time for class D is reduced by 20% and the time for class C is increased by 10% (assuming no other changes)? b) If we want to reduce the total execution time by 20% by optimizing class A only, what is the arget execution time of class A instructions in order to achieve the reduction (assuming all other nstructions are not changed)? c) Can the total time be reduced by 25% if we only optimize class B? Use calculation to justify vour answer.
