Given information
Provided that in a year a sample of tritium-3 decayed to 
of its original amount.
Need to calculate the time taken to decay to 
of its original amount
Step-by-step explanation
Step 1.
Note that the decay equation is given by 
, where 
is the amount remains after 
years and 
is the initial amount.
Observe that here, 
Therefore, by decay equation for
