Two radioacitve nuclei P and Q, in a given sample decay into a stable nucleus R. At time t=0, number of P species are 4 `N_(0)` and that of Q are `N_(0)`. Half-life of P (for conversion to R) is 1 min, where as that of Q is 2 min. Initially there are no nuclei of R present in the sample. When number of nuclei of P and Q are equal, then the number of nuclei of R present in the sample would be
