A new radioactive element is discovered called Obama45. This element decays into Nohea43 (a rare element called Nohealthcareandatleastfivemoreyearsinafghanistan) with a half life of 10 years. If a fossil is obtained and tested for these radioisotopes we find that ratio of Obama45 to Noheal43 is 1:15. How old is the fossil using radiometric dating.

a) 10 years
b) 20 years
c) 30 years
d) 40 years
e) 50 years
