If you kill 5% of the population every year from 1933 to 1945, how much of the initial population >you end up killing?

This is the simple math problem you stated and the answer is 46%, not 60%. Nobody does the calculation the way you do. Or you think that a simple math problem has two contradictory answers? Show me a single example that someone does the calculation the way you do to answer such a problem, you have the whole internet. I accept my error if you find it.
