Hello. You said

The second pair of methods will not compile correctly, since their method signatures are same

Is return type not a part of the method signature?
The second pair is:
2.
void perform_work(int time){ }
int perform_work(int speed){return speed ;}

No, the return type is never a part of a method signature. Which book are you following? It should have explained that.

The book of Mala Gupta . No, it was not there. Thank you! And the order of arguments changes the signature?

Yes, order of parameter types is important. parameter names are not important.
