A radioactive sample decays through two different decay processes `alpha`-decay and `beta`-decay is `6h`. What will be the ratio of number of radioactive nuclei present after `6 h`?.

A radioactive sample decays through two different decay processes alpha -decay and beta -decay. Half-life time for alpha −decay is 3h and half-life time for beta −decay is 6h . What will be the ratio of number of initial radioactive to the number of nuclei present after 6 h ?.
