Question:
The rubidium isotope 8737Rb, a β emitter with a half-life 4.75 × 1010yr, of is used to determine the age of rocks and fossils. Rocks containing fossils of ancient animals contain a ratio of 8737Sr to 8737Rb of 0.0260. Assuming that there was no 8738Sr present when the rocks were formed, estimate the age of these fossils.

I believe everyone should try to be strong at logic and have good reading habit. Because If you possess these two skills, no matter what difficult situation is, you will definitely find a perfect solution out of it. While logical ability gives you to understand complex problems and concepts quite easily, reading habit gives you an open mind and holistic approach to see much bigger picture.
So guys, I always try to explain any concept keeping these two points in my mind. So that you will never forget any more importantly get bored.
Last but not the least, I am finance enthusiast. Big fan of Warren buffet for long term focus investing approach. On the same side derivatives is the segment I possess expertise.
If you have any finacne related doubt, do reach me out.
