    Explanation:

    By the rule of alligation:
    Cost of 1 kg rice of 1st kind                  Cost of 1 kg rice of 2nd kind 

                  720                                                        570

                                                  630

                   60                                                          90

    Required ratio = 60 : 90 = 2 : 3

    Hence, option 2 is the correct answer.
