Question
The half-life ofg the radioactive radon is 3.8 days. The time, at the end of which 1/20t of the radon sample will remail undecayed, is (given log10e = 0.4343)
Options
A.3.8 days
B.16.5 days
C.33 days
D.76 days
Solution
Using N = N0e-λt
where
∴ 
Solving this equation with the help of given data we find :
t = 16.5 days
∴ Correct option is (b).
