Two radioactive materials X1 and X2 have...

Two radioactive materials `X_1` and `X_2` have decay constants `10 lamda` and `lamda` respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of `X_1` to that of `X_2` will be `1//e` after a time.

`1/(10 lamda)`

`1/(11 lamda)`

`11/(10 lamda)`
