A) 29 years
B) 24 years
C) 64 years
D) 12 years
Correct Answer: B
Solution :
[b] Effective half life is calculated as \[\frac{1}{T}=\frac{1}{{{T}_{1}}}+\frac{1}{{{T}_{2}}}\] \[\frac{1}{T}=\frac{1}{16}+\frac{1}{48}\Rightarrow T=12\] years Time in which \[\frac{3}{4}\] will decay is 2 half-lives = 24 yearsYou need to login to perform this action.
