Let the original electricity units used without energy savings be 100 units.
After the first energy saving improvement, the energy used
is 100 U - 25% of 100 U = 75U
After the second energy saving improvement, the energy used is
75U - 55% of 75 U = 33.75 U
After the third energy saving improvement, the energy used is
33.75 U - 20% of 33.75 U = 27U
Therefore, the overall percentage saving is 100U - 27U = 73U or 73%
