Hi,
I want to know about mathematical formula to find / estimate the battery life of Bluetooth beacon containing NRF8240. If chip is transmitting at +8 dBm and have 1000 ms of broadcast interval.

It still depends on:
In other words, it is next to impossible to estimate, and your best option is to make a prototype and measure the average current yourself. You can have a peek at this power calculator though. It is close to what you need, but note that it is made for nRF52832.
As I mentioned, it is impossible to give an estimate based on only the two parameters you have given.
There are two types of voltage converters in the nRF52; Linear Dropout converters and DC-to-DC converters. DCDC converters are usually more power efficient, but requires additional external components (making your device slightly larger and more expensive). Here is more documentation.
By radio protocol I mean whether you are using BLE, 802.15.4, etc.
