Given-
Half life of 
C 
years
As we know -
Where
Mass of radioactive carbon after a time period "t"
initial mass of radioactive carbon
radioactive decay constant
time
First we will find the value of "k"
On solving, we get -
Now, when mass of 14C becomes 
% of the plant material on earth today, then its age would be
years
