1. Nguva yekudzoka
Tisati tapinda muhurukuro, ngationgororei "nguva yekudzoka." Mune chidzidzo chedu chakapfuura, kamwe mumakore makumi mashanu = kamwe mumakore makumi mashanu? - Semuenzaniso, kune mhepo mitoro ine nguva yekudzoka kwemakore makumi mashanu, iyo yegore inopfuura mukana ndeye 2%; Kune mhepo mitoro ine nguva yekudzoka kwemakore zana, iyo yegore rinopfuura mukana ndeye 1%.

Kune mutoro wemhepo une mukana wepagore Naizvozvo, mukana wakanyanya kwazvo wekumhanya kwemhepo mumakore n makore anogona kuverengerwa neye inotevera formula:

Sekureva kweiyi formula: yeiyo mhepo mutoro mumakore makumi mashanu ekudzoka, iyo gore rinopfuura mukana uri p = 2%, uye mukana wakanyanya mukati memakore makumi mashanu ndewekuti:

Iyo 100-Year transcendence mukana inowedzera ku:
