Answer» Two species of radioactive atoms A and B are mixed together. Initial number of active atoms of A and B are $N_{0}$ and $2 N_{0}$ with decay constant $λ$ and $\frac{λ}{3}$ respectively. Mean (average) life of mixture is $\frac{n}{λ}$ , then n is (Write upto two digits after the decimal point.)
