The rate of decay of a radioactive body at any time is proportional to its mass present at that time. If the mass of body is

100 \mathrm{gms}

after one hour and

80 \mathrm{gms}

after two hours, then the initial mass of radioactive body is ........ .

View answer and explanation

Correct option: C

125
