Question

A radioactive sample consits of two distinct species
having equal number of atoms (No) initially . The mean life of one species in t and other is 5t
the decay product in both cases is stable the total
number of radioactive nuclei at t =5t is

i) No (e^4+1)/e^5

ii) No(e^5+1)/e^4

iii)No(e^3 + e^2 /e^5)

iv) No (e+1)/e^5)​
